util: Fix pa_get_binary_name() on Debian/kFreeBSD

Debian GNU/kFreeBSD uses a FreeBSD kernel and GLIBC,
it #defines __FreeBSD_kernel__, but not __FreeBSD__ nor __linux__
Debian GNU/kFreeBSD does have a /proc/self/exe

FreeBSD #defines __FreeBSD__ and __FreeBSD_kernel__

http://stackoverflow.com/questions/1023306/finding-current-executables-path-without-proc-self-exe and
http://stackoverflow.com/questions/933850/how-to-find-the-location-of-the-executable-in-c have some
background info
