Allow uid and gid to be terms in BPF filters by first breaking the connection between filter terms and PERF_SAMPLE_xx values. Calculate the uid and gid using the bpf_get_current_uid_gid helper, rather than from a value in the sample. Allow filters to be passed to perf top, this allows: $ perf top -e cycles:P --filter "uid == $(id -u)" to work as a "perf top -u" workaround, as "perf top -u" usually fails due to processes/threads terminating between the /proc scan and the perf_event_open.
