Add GAP distro tests

[lgoettgens]

Resolves #1065.

This is dependent on #1066 and thus includes it.

I've used the ugly hack from oscar-system/GAP_pkg#15 in GAP.Packages.test to avoid GAP packages exiting the process after running their tests. This function could be moved to a package extension on Test once the minimum required julia version is bumped to 1.8.

IMO this shouldn't run on every commit in every PR, as it produces >150 jobs. But I have kept it here for now such that in this PR, we can already see it running.

	output = sprint(print, "gap-packages=", filter(name -> startswith("d", name) || startswith("f", name), readdir(artifact"gap_packages")));
	output = sprint(print, "gap-packages=", readdir(artifact"gap_packages"));

once we are happy with how this works, we can enable it to test the whole distro and not just ~10 packages

[lgoettgens]

The remaining failures (for packages starting with d or f (random two letters)) seem to be more or less genuine:

• design: its (transitive) dep GRAPE has a build error
• difsets: its (transitive) dep GRAPE has a build error
• fining: its (transitive) dep GRAPE has a build error
• francy: its (transitive) dep zeromqinterface has a build error

So I think that this is ready to review now.
