perf tools: Check existence of _get_comp_words_by_ref when bash completing
The '_get_comp_words_by_ref' function is available from the bash
completion v1.2 so that earlier version emits following warning:
$ perf re<TAB>_get_comp_words_by_ref: command not found
Use older '_get_cword' method when the above function doesn't exist.
