Merge branch 'bpf-reject-bpf_timer-for-preempt_rt'

====================
bpf: Reject bpf_timer for PREEMPT_RT
While running './test_progs -t timer' to validate the test case from
"selftests/bpf: Introduce experimental bpf_in_interrupt()"[0] for
PREEMPT_RT, I encountered a kernel warning:
BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48
To address this, reject bpf_timer usage in the verifier when
PREEMPT_RT is enabled, and skip the corresponding timer selftests.
Changes:
v2 -> v3:
* Drop skipping test case 'timer_interrupt'.
* Address comments from Alexei:
* Respin targeting bpf tree.
* Trim commit log.
v1 -> v2:
* Skip test case 'timer_interrupt'.
