Drop our local sstrip copy and use the current ELFKickers upstream
version.
Patch the original makefile in order to avoid building elftoc, since it
fails with musl's elf.h. This is fine, since we only need sstrip anyway.
Finally, add the possibility to pass additional arguments to sstrip and
pass -z (remove trailing zeros) by default, which matches the behaviour
of the previous version.

Comparing the in tree stored source file of sstrip suggests it's version
2.0[0], reflect that in the Makefile.
Motivation is the tracking of changes in the buildsystem, which requires
versioning of packages.
