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.
