gbproxy_test.c: fix mobile identity test data

Fix the final nibble of all IMSI BCD digits to 0xf, since it is a filler digit.

The encoded IMSI has an even amount of digits (14) and must contain a 0xf
filler nibble at the end. The test data looked correct due to repeated '1'
digits.

wrong hex: 11 12 13 14 15 16 17 18
correct:   11 12 13 14 15 16 17 f8
order:     1T 32 54 76 98 ba dc Xe  T = type, X = filler, 1..e = 14 digits

This error was found when applying the new osmo_mobile_identity API.
