selftests/bpf: Add test for unpinning htab with internal timer struct
Add test to verify that unpinning hash tables containing internal timer
structures does not trigger context warnings.
Each subtest (timer_prealloc and timer_no_prealloc) can trigger the
context warning when unpinning, but the warning cannot be triggered
twice within a short time interval (a HZ), which is expected behavior.
