bch: don't use __BSD_VISIBLE to test for fls

Browse Source 
Commit 4ecc988301bc8e981e6d7538c57cdb3aa82f7c1d assumes fls is in libc
if __BSD_VISIBLE is defined.  This appears to only be true on FreeBSD
and DragonFlyBSD.  OpenBSD defines __BSD_VISIBLE and does not have fls
in strings.h/libc.

Switch the test for __BSD_VISIBLE to one for __DragonFly__ and
__FreeBSD__ to unbreak the build on OpenBSD.
