perf probe: Show in what binaries/modules probes are set
Show the name of binary file or modules in which the probes are set with
--list option.
Without this change;
# ./perf probe -m drm drm_av_sync_delay
# ./perf probe -x perf dso__load_vmlinux
# ./perf probe -l
probe:drm_av_sync_delay (on drm_av_sync_delay)
probe_perf:dso__load_vmlinux (on 0x000000000006d110)
With this change;
# ./perf probe -l
probe:drm_av_sync_delay (on drm_av_sync_delay in drm)
probe_perf:dso__load_vmlinux (on 0x000000000006d110 in /kbuild/ksrc/linux-3/tools/perf/perf)
