tests: posix: common: remove test_clock_gettime_rollover

[cfriedt]

The logic in this test only worked for a subset of configurations with 64-bit counters. Remove the test to ensure the suite passes on all platforms.

Fixes #53605

Just wondering why it's not enough to skip this test on the platform with non-64-bit counters? Like if CONFIG_TIMER_HAS_64BIT_CYCLE_COUNTER isn't set?

That probably would work (at least for a subset of boards with 64-bit counters) but it would also be nice if there were some API / config consistency among systems with < 64-bit counters.

Currently, it's "this clock rolls over sometime after 365 days, maybe", which is a bit slippery.

I'd rather not codify a test here if we are missing some critical pieces of info and left guessing about them due to lack of abstraction.

However, I would be perfectly happy to review another PR on this subject if that were to appear.
