bsc: more SI2quater EUTRAN ARFCN tests

Add more EUTRAN ARFCNs, reaching the maximum allowed amount.

Add tests with 12, 23, 42 EARFCNs, just for the sake of testing some arbitrary
numbers.

Add tests with 32 and 33 EARFCNs because before osmo-bsc
Iabeed10053ee5899b4def3509aedd25abb2410a9, only 32 EARFCNs could be stored by
osmo-bsc.

Add a test with 48 EARFCNs to verify the maximum amount of EARFCNs and maximum
amount of SI2quater multiplexes works as expected.

Add a test with 49 EARFCNs to verify the VTY error response when adding too
many EARFCNs, and showing that osmo-bsc still sends 16 SI2quater with 48
EARFCNs.

Depends: Iabeed10053ee5899b4def3509aedd25abb2410a9 (osmo-bsc)
