wayland: add ptest

Sadly, meson makes it very difficult to install tests: the test
configuration is written into host-specific binary files, which
can't be transferred to the target. (unlike autotools where
at least everything happens via Makefiles which can be patched
and tweaked via sed and env vars)

So the configuration has to be entirely recreated in shell.
I managed this for wayland, but weston proved too difficult.

I had filed bugs asking upstream to make the tests installable:
