config/git: import suckless sbase

i currently use the output of sha512sum in several
places of xbmk, which is a bit unreliable in case
output changes.

other cases where i use util outputs in variables
are probably reliable, because i'm using mostly
posix utilities in those.

to mitigate this, i now import suckless sbase, which
has a reasonable sha512sum implementation.

*every* binary it builds is being placed in build.list,
because i'll probably start using more of them.

for example, i may start modifying the "date"
implementation, adding the GNU-specific options that
i need as mentioned on init.sh

i'm importing it in util/ because the sha512sum
util is needed for verifying project sources, so
if sbase itself is a "project source", that means
we can into a chicken and egg bootstrapping problem.

this is sbase at revision:

+.Op Ar file ...
+.Sh DESCRIPTION
+.Nm
+searches the input files for lines that match the
+.Ar pattern ,
+a regular expression as defined in
+.Xr regex 7 or
+.Xr re_format 7 .
+By default each matching line is printed to stdout.
+If no
+.Ar file
+is given
+.Nm
+reads from stdin.
+.Sh OPTIONS
+.Bl -tag -width Ds
+.It Fl E
+Match using extended regex.
+.It Fl F
+Match using fixed strings.
+Treat each pattern specified as a string instead of a regular
+expression.
+.It Fl H
+Prefix each matching line with its filename in the output.
+This is the default when there is more than one file specified.
+.It Fl c
+Print only a count of matching lines.
+.It Fl e Ar pattern
+Specify a pattern used during the search of the input: an input
+line is selected if it matches any of the specified patterns.
+This option is most useful when multiple -e options are used to
+specify multiple patterns, or when a pattern begins with a dash.
+.It Fl f Ar file
+Read one or more patterns from the file named by the pathname file.
+Patterns in file shall be terminated by a <newline>.
+A null pattern can be specified by an empty line in pattern_file.
+Unless the -E or -F option is also specified, each pattern shall be
+treated as a BRE.
+(`-').
+.It Fl h
+Do not prefix each line with 'filename:' prefix.
+.It Fl i
+Match lines case insensitively.
+.It Fl l
+Print only the names of files with matching lines.
+.It Fl n
+Prefix each matching line with its line number in the input.
+.It Fl q
+Print nothing, only return status.
+.It Fl s
+Suppress the error messages ordinarily written for nonexistent or unreadable
+files.
+.It Fl v
+Select lines which do
+.Sy not
+match the pattern.
+.It Fl w
+The expression is searched for as a word (as if surrounded by '\\<' and '\\>').
+.It Fl x
+Consider only input lines that use all characters in the line excluding the
+terminating <newline> to match an entire fixed string or regular expression to
+be matching lines.
