[PATCH] osmo-gsm-tester[master]: bsc: Allow tests to select network encryption

[Pau Espin Pedrol]

Review at  https://gerrit.osmocom.org/3604

bsc: Allow tests to select network encryption

Nowadays encryption parameter in bsc needs to be set to the same cipher as
the one specified in msc, otherwise the cipher negotation will fail.

See OS#2461 for more information on the matter.
