Move libosmogsm TS 44.060 declarations under include/osmocom/gsm/

Currently there's a big mess where include dir osmocom/gprs/ is used by
both libosmogsm and libosmogb.
Most of the header files under osmocom/gprs/ are actually all the
headers of libosmogb (there's no osmocom/gb/ dir). But a couple files
are actually RLC/MAC (TS 44.060) related are are also stored in there.
Those files have no relation/use in Gb, and are actually interused with
GSM (eg System Information 13 Rest Octets).
Hence, it makes sense to have the RLC/MAC related parts inside
osmocom/gsm/ as they should be in libosmogsm (and they actually are,
see gprs_rlc.h function implemented in src/gsm/gsm48_rest_octets.c).

The fact that some libosmogsm headers were placed in osmocom/gprs
instead of osmocom/gsm already created some issues, like
libosmocore.spec.in putting "%_includedir/%name/osmocom/gprs/" under
libosmogb, which is wrong.

As a first step to fix the mess, we move the 2 RLC/MAC headers currently
under osmocom/gprs/{gprs_rlc,protocol/gsm_04_60}.h under a single header
gsm/protocol/gsm_44_060.h
The two old headers are left existing for backward compatibility and now
simply include the new libosmogsm header, plus a warning asking users to
switch to the new header so we can eventually get rid of them.
This means libosmogb depends on libosmogsm, which is fine and was
already the case beforehand (libosmogb using functions like
gsm48_encode_ra() and linking against it in src/gb/Makefile.am).
