Implements a non-modifying GNU basename() function for libunwindstack

This function is added in compat.h, which provides functions that are
available within libunwindstack's normal build environment but
unavailable within its Chromium build environment. We call the
function "compat_basename".

This function isn't available in Android NDK version 16 (it was first
made available in 23, as per https://bit.ly/31Gkyl9). Although there's a
POSIX basename() available via <libgen.h>, this function has different
behavior with regards to trailing slashes and can also modify its
argument under some circumstances.
