bsc: change encryption a5 via VTY where needed 

Do not assume that osmo-bsc.cfg contains "0 1 3 4" for master and "0 1 3"
for latest anymore. An upcoming test will need to change the value as
the test runs and needs a defined value to reset to.

Assume that osmo-bsc.cfg contains "0 1 3" and change it to "0 1 3 4"
only for TC_ciph_mode_a5_4.
