tests: Add test for libmateweather

This is the first automated test for libmateweather, so it is named
generically to be extended.

The upstream test_named_timezones test is omitted since libmateweather
does not have the NAMED_TIMEZONE location level.

Adapted from libgweather: https://gitlab.gnome.org/GNOME/libgweather/-/commit/2373f56f
