pcu: Drop test TC_t3169 

This test was added a long time ago to test what used to be the previous
early implementation of T3169, which didn't follow specs as per TS
44.060.
Since recently, osmo-pcu supports tracking UL PDCH blocks and hence
properly implementing N3101 and N3101, finally also implementing T3169
correctly.
The counters N3101/3 and timer T3169 are already being tested in
following tests:
TC_n3101_max_t3169
TC_n3103_max_t3169

Since osmo-pcu I2cec531e2633281b88f69ba065c0105580c81076, time-based
T3169 is dropped and TC_t3169 doesn't pass anymore, since it had wrong
expectancies (because it's not sending RTS to osmo-pcu, hence not
triggering USF/RRBP N3101/3 timeouts).
