search: Relax folder restrictions to allow gvfs locations.

The real path for gvfs mounts is /run/user/nnnn/gvfs/*, so remove
the /run path from the skip list - in hindsight there may be more
users here than assumed (see Warpinator link).

The zero-size file check was originally intended to catch /proc
files without having to check each folder's filesystem type, but
since we're skipping /proc explicitly, it's not necessary, and
smb folders (and probably others) report 0 size.

Fixes #3273
