os: First check for __GLIBC__ and then for PIPE_OS_BSD

Fixes FTBFS on kfreebsd-*

Debian GNU/kFreeBSD doesn't provide getprogname() since it uses stdlib.h
from glibc. Instead it provides program_invocation_short_name from glibc.

You can find the same order in src/mesa/drivers/dri/common/xmlconfig.c
