Fix the pidof comm and cmdline tests.
If we have a 15-byte name, we don't know whether comm actually matches
or is a truncated form of a longer name that has a common prefix.
For example, with "this-is-a-very-long-name-that-is-too-long", we shouldn't
match "this-is-a-very-" (but the old code would).
The cmdline code was also broken on Android because it used basename(3)
rather than getbasename. This doesn't affect glibc because there's a
workaround in portability.h to ensure that we get the non-POSIX basename(3)
with glibc but then a non-glibc section that ensures everyone else gets
POSIX basename(3). That should probably be removed (and maybe `basename`
poisoned) to prevent similar mistakes in future.
