chore(linux): Workaround: Don't run Wayland tests

This is a workaround for running the tests on Ubuntu 22.04 Jammy.
For 16.0 we don't have everything in place to successfully run
the tests with Wayland. Additionally the Wayland support in Keyman
is still incomplete. So we disable the Wayland tests in order to
be able to get successful builds of 16.0.
