app-forensics/zzuf: add 0.15_p20220529

As far as upstream is concerned this snapshot is identical to _p20190208
apart from some typos in the documentation having been fixed. On the
Gentoo side, however, this ebuild adds support for building with
-Werror=implicit-function-declaration along with removing the previously
hard-coded '-g -O2' from compiler flags.

Closes: https://bugs.gentoo.org/871558
