gallium: Add support for BSD operating systems, tested with FreeBSD

BSD supports pipe in the same way as linux hence options which
are safe for linux are also safe for BSD. Define PIPE_OS_BSD in
include/pipe/p_config.h and adjust the defines to make use of it.

Also define MAP_ANONYMOUS for BSD systems which use MAP_ANON
