Continuation of previous FreeBSD-related fix for Galera SST scripts

Paths are set to "canonical" form and historical practice where
/lib comes before /usr/lib and /bin comes before /usr/bin. This
eliminates the need to skip setting LD_LIBRARY_PATH for FreeBSD,
which may help those users whose LD_LIBRARY_PATH is not configured
properly.
