mate-extra/mate-sensors-applet: Fix an invalid pointer crash

Fix an invalid pointer crash with glib 2.83.2
The typecast to non-const gchar produced invalid pointer errors on free() with glib 2.83.2

Not entirely sure why this wasn't included with 1.28.0 release, however as a Gentoo user has reported it resolves the issue for them and Fedora are using the same patch in https://bugzilla.redhat.com/show_bug.cgi?id=2326719 then I see no issue to cherrypick this before the 1.28.1 release.
