Subject: [PATCH] Q{Temporary,}File: make QStandardPaths use test mode

The moveToTrash tests, on XDG platforms, would be trashing to
~/.local/share/Trash. Unlike Windows and Apple systems, the XDG trash
spec creates two files and these tests weren't deleting both of them, so
we had a slow increase of left-over files in ~/.local/share/Trash/info.

Cleaning up ~/.qttest is left as an exercise for the users. For example,

 $ cat ~/.config/user-tmpfiles.d/qttest.conf
 #Type Path                            Mode User Group Age         Argument
 e     %h/.qttest                      0700 -    -     1w

Pick-to: 6.5 6.2
