Get rid of osmo_str_tolower() use inside libosmocore code

There's no real good reason for using that function (static buffer)
instead of osmo_str_tolower_buf(local buffer), so let's use the later.
In any case, we get rid of TLS variables in those places, which is a
performance improvement.
It will also allow later shrinking of those buffers if we decide to
define maximum logging category and level name length.
