Bug #192341 - Eliminate the dependency on py-freebsd by implementing

it's chflags() and lchflags() functions as wrappers around the
chflags command (which should always be available in any case). The
functions are only called when merging/unmerging files that actually
have flags set so the performance difference should be negligible.
