select: Rename BSC_FD_* constants to OSMO_FD_*

The naming of these constants dates back to when the code was private
within OpenBSC.  Everything else was renamed (bsc_fd -> osmo_fd) at
the time, but somehow the BSC_FD_* defines have been missed at the
time.

Keep compatibility #defines around, but allow us to migrate the
applications to a less confusing naming meanwhile.
