remove sgsn, gbproxy and gtphub from openbsc.git
The GPRS related programs osmo-sgsn, osmo-gtphub and osmo-gbproxy have been split off into the separate osmo-sgsn repository, which can be found at git://git.osmocom.org/osmo-sgsn.git http://git.osmocom.org/osmo-sgsn/ This is technically unrelated but conceptually part of the larger NITB-split activities. I did a brief log of all changes in src/gprs and couldn't find any commits that we might have applied here but which are missing from osmo-sgsn.git.
