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:

+sbase - suckless unix tools
+===========================
+
+sbase is a collection of unix tools that are inherently portable across
+UNIX and UNIX-like systems.
+
+The complement of sbase is ubase[1] which is Linux-specific and provides
+all the non-portable tools. Together they are intended to form a base
+system similar to busybox but much smaller and suckless.
+
+Building
+--------
+
+To build sbase, simply type make. You may have to fiddle with config.mk
+depending on your system.
+
+You can also build sbase-box, which generates a single binary containing
+all the required tools. You can then symlink the individual tools to
+sbase-box or run: make sbase-box-install
+
+To run the tools for sbase-box directly use: sbase-box cmd [args]
+
+Ideally you will want to statically link sbase. If you are on Linux we
+recommend using musl-libc[2].
+
+Portability
+-----------
+
+sbase has been compiled on a variety of different operating systems,
+including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.
+
+Various combinations of operating systems and architectures have also
+been built.
+
+You can build sbase with gcc, clang, tcc, nwcc and pcc.
+
+Status
+------
+
+The following tools are implemented:
+
+'#'  -> UTF-8 support, '=' -> Implicit UTF-8 support, '*' -> Finished,
+'|'  -> Audited,       'o' -> POSIX 2013 compliant,   'x' -> Non-POSIX,
+'0'  -> NUL handling,  '()' -> Petty flag
