QMimeDatabase: don't stat() something that isn't a local file

We must check that the path is an actual file on the filesystem before
using native APIs. This regression was introduced by commit
047d8f36de45ebb318726167f941b0dbc64754ba.

[ChangeLog][QtCore][QMimeDatabase] Fixed a regression from 6.4.0 that
made certain QMimeDatabase functions that inspected file contents to fail
on Unix systems, if the file was not a native file (e.g., a Qt resource).

Fixes: QTBUG-110707
Pick-to: 6.4 6.5
