ANDROID: sched/core: Optimize vendor hook placement

Browse Source 
Currently, the tick_entry vendor hook in the scheduler tick path is
called before the rq clock is updated.
Change the vendor hook placement to after the clock update so that an
updated clock value is used.

Fixes: ca60d78542 ("Revert "Revert "ANDROID: Sched: Add restricted
vendor hooks for scheduler""")
