Dynamically enable filename completion in BASH instead of calling _filedir

`_filedir` is a function provided by the bash-completion project, not by BASH
itself. I was seeing inconsistent completion results with multi-word/escaped
results as the completer was returning filenames, but wasn't in `filenames`
mode.

I went to enable filename completion mode to get better completion
behaviour for paths from `_filedir`, but it turns out the completion hook function
can just be switched to BASH's default file/dir completion behaviour instead.
