perf tools: include basename for non-glibc systems

perf uses the glibc version of basename(), by defining _GNU_SOURCE,
including string.h and not including libgen.h. The glibc version of
basename is better than the POSIX version since it does not modify its
argument.

Android has only one version of basename which is defined in libgen.h.
This version is the same as the glibc version.

Error on Android:
util/annotate.c: In function 'symbol__annotate_printf':
util/annotate.c:503:3: error: implicit declaration of function 'basename'
[-Werror=implicit-function-declaration]
util/annotate.c:503:3: error: nested extern declaration of 'basename'
[-Werror=nested-externs]
util/annotate.c:503:14: error: assignment makes pointer from integer without
a cast [-Werror]

On Android libgen.h should be included to define basename.
