selftests/bpf: Test pinning bpf timer to a core
Now that we support pinning a BPF timer to the current core, we should test it with some selftests. This patch adds two new testcases to the timer suite, which verifies that a BPF timer both with and without BPF_F_TIMER_ABS, can be pinned to the calling core with BPF_F_TIMER_CPU_PIN.
