vty: allow enabling freq. hopping regardless of the feature vector

The hard-coded per-BTS feature vector for osmo-bts currently lacks
BTS_FEAT_HOPPING, and this is unlikely to change, because only the
recent osmo-bts-trx does support freq. hopping, while the other
(DSP based) back-ends do not seem to be capable of doing it.

Let's allow enabling freq. hopping regardless of the feature vector,
so either it would work if it's supported, or the BTS would reject
Set Channel Attributes message by sending NACK on the A-bis/OML.
