CI build failures for type_check example

[jameskermode]

The CI build configuration problems should now be fixed in #241, however it appears they were masking a problem with the type_check example which does not build in CI on either Linux or macOS. I dug into this a bit and reproduced manually (testing on MacOS with gfortran 14.2). Error is:

There seem to be mismatched int and real kinds in the generated wrappers. Editing the generated f90wrap_main.f90 manually as follows produced something that compiled:

@danbeibei please can you take a look?

Looks like the kind.map was not included in the Makefile.meson of examples/type_check. There was a second issue in examples/return_array where I replaced the tests.py by test.py. Let's see now if it builds on #243 .
