Fix test-build GitHub Action (#67)

* Fix bugs in the .yml file

* Fix test step in the GitHub CI

When using out of source build all `make` rules should be executed in the corresponding directory (e.g. `_build`)

* Add CI step to test TREXIO on MacOS

* Explicitly provide gcc-10 and gfortran-10 to configure
