osmo-sgsn was installing a sysvinit script but it wasn't inside
the INITSCRIPT_PACKAGES so it would not be started by default.
Use the already existing INITSCRIPT_PARAMS/INITSCRIPT_NAME variables
for the osmo-sgsn.
Fixes: SYS#366
This might require to rebuild the freshly built openggsn to
fix the libgtp0 depedency. I had this issue on Dora without
a PRServer. I am not sure it applies to edison or other configs.
Bump the PR of OpenBSC to force a rebuild of the SGSN.
Fixes: SYS#176
Make the start/stop of the NITB, BSC and MGCP HW work, remove the
force-reload option as it didn't do anything and omit writing counters
into the database.
