Fix extracting entries with file paths that contain unicode characters

Libarchive stores most paths internally in a multistring that can
contain a combination of a wide character string, multibyte string in
current locale or unicode string encoded as UTF-8. Try to retrieve and
set a variant of the string with the correct encoding when converting
libarchive strings to/from Qt string classes.
