bsc/nitb: Allow to set the GPRS mode through the ctrl command

Create a control command to read and modify the gprs mode. Use
the get_string_value to indicate if the value was found or not.
This is useful for the ctrl interface where I didn't want to
replicate "none", "gprs" and "egprs". Share code to verify that
a BTS supports the mode.
