pcu: Relax some CS/MCS expectancy checks

Previous commit implemented the CS/MCS verification, and hence now some
tests fail because they had too restrictive checks.

In theory the verifications could be done so restrictive by configuring
the PCU accordingly at the start of the test, but we are not
really interested in checking the exact CS/MCS in these tests, only
checking if GPRS/EGPRS is being used.
