Legacy compat: we used to not check the BTS codec-pref settings upon assignment
until we added checks for the BTS codec-pref in osmo-bsc

I285234e9c81de74d9fb9907fca2c443b08537435, "codec_pref: check bts codec
support". From that commit onwards, config setups without a 'codec-pref'
potentially stop working (like all osmo-gsm-tester runs just did), because with
no codec-pref settings, now only FR is permitted, while before the patch, we
would allow any codecs as long as MSC and the overall BSC config agree on them.
So, upon BTS initialization, enable all codecs. These get reset to a more fine
grained selection IF a 'codec-support' config appears in the config file (see
bsc_vty.c).
