For testing the ps4 we have to run the tests on windows. Currently we
use a msys2 shell but that causes endless problems with paths being
interpreted incorrectly.

I am working on getting all the posix tests to work with the builtin
executor instead. I am adding missing features, but in some cases it
seems better to change the test. So far the only feature that I think
is better avoided than implemented for now is subshells.

Cheers,
Rafael
