libapparamor: Define a portable version of gnu basename

Browse Source 
Since musl 1.2.5, basename(3) prototype is only provided in libgen.h
(as mandated by POSIX) and not in strings.h. Also there is a major
difference between the gnu basename and the one defined in libgen.h,
the latter modify the argument string making them incompatible.

Fix this by defining a portable version of basename using strchr.
