Define _GNU_SOURCE, required for O_CLOEXEC on uClibc

Browse Source 
When building sysklogd on a uClibc system we must define _GNU_SOURCE to
get O_CLOEXEC.

Since _GNU_SOURCE is also required for asprintf() with GLIBC, as used by
the pidfile() replacement function, we drop it from there and rely on
AM_CPPFLAGS for all sources.
