ANDROID: FIPS: remove some random core symbols

The symbols add_random_ready_callback and del_random_ready_callback went
away in 5.15.44, so remove them from the list first so that the checker
doesn't get confused when it can no longer find them.

Fixes: 6da877d2 ("random: replace custom notifier chain with standard one")
