selftests/bpf: Check for timeout in perf_link test
Recently perf_link test started unreliably failing on libbpf CI:
* https://github.com/libbpf/libbpf/actions/runs/11260672407/job/31312405473
* https://github.com/libbpf/libbpf/actions/runs/11260992334/job/31315514626
* https://github.com/libbpf/libbpf/actions/runs/11263162459/job/31320458251
Part of the test is running a dummy loop for a while and then checking
for a counter incremented by the test program.
Instead of waiting for an arbitrary number of loop iterations once,
check for the test counter in a loop and use get_time_ns() helper to
enforce a 100ms timeout.
