ts_31_102: fix testcase for EF_ePDGSelection

the testcase EF_ePDGSelection has a wrong testvector in the plmn field.
This test vector is accepted because there is a complementary error in
pyosmocom. However, the root problem got fixed (see depends), which means
that the test vector of EF_ePDGSelection now needs to be updated.

Depends: pyosmocom.git: I3811b227d629bd4e051a480c9622967e31f8a376
