Revert "gnome-weather: remove absolute path in desktop entry"

This mostly reverts commit dc27833 (except the "--replace" ->
"--replace-fail" part).

Same as d37e098 ('Revert "gnome-maps: remove absolute path in
desktop entry"'), this is not a desktop entry and dbus files should
contain full path to the application to start.

Closes #357955.

(cherry picked from commit f765c4f)
