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:

+The following list of commands is taken from the toybox roadmap[0] and
+has been stripped down  accordingly.  Commands that belong to ubase[1]
+are not listed here as well as commands that fall outside the scope of
+sbase such as vi and sh are also not listed here.
+
+at
+awk
+bc
+diff
+patch
+stty
+
+If you are looking for some work to do on sbase, another option is to
+pick a utility from the list in the README which has missing flags or
+features noted.
+
+What also needs to be implemented is the capability of the tools to
+handle data with NUL-bytes in it.
+
+The return values of mdcheckline() in crypt.c need to be fixed (0 -> success,
+1 -> error).
