perf trace: Free strings in trace__parse_events_option()

Browse Source 
ASan reports several memory leaks running:

  # perf test "88: Check open filename arg using perf trace + vfs_getname"

The fourth of these leaks is related to some strings never being freed
in trace__parse_events_option.

This patch adds the missing frees.
