core: support mpv directory itself as a valid location for config files on Windows

This prefers ./ on Windows if-and-only-if the file being searched for
already exists there. (If the mpv directory is non-writable, the result
is still intended behavior.) This change is transparent to most users
because the user has to move the config files there intentionally, and
if anything, not being detected would be the surprising behavior.
