build: bump Meson requirement to 0.52.1

Fixes: https://gitlab.freedesktop.org/wayland/weston/-/issues/296

The conclusion (quite a while ago, too) was that requiring Meson 0.52 is
fine. Mesa does that too. Bump the requirement to 0.52.1 which is the
last release of the 0.52 series.

This allows all issues listed in #296 to be worked on. It also allows
switching to TAP in the test suite for more detailed reports.
