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:

+argument and for each directory in the file hierarchy rooted in directory
+argument.
+If no
+.Ar file
+is specified, the block usage of the hierarchy rooted in the current directory
+is displayed.

+.It Fl a
+Display an entry for each file in the file hierarchy.
+.It Fl s
+Display only the grand total for the specified files.
+.It Fl d Ar depth
+Maximum directory depth to print files and directories.
+.It Fl h
+Enable human-readable output.

+By default all sizes are reported in 512-byte block counts.
+The

+Always dereference symbolic links while recursively traversing directories.
+.It Fl P
+Don't dereference symbolic links.
