Make the module semi-functional

[AlexDaniel]

I attempted to fix the module during the squashathon.

So it compiles and works now, and some tests in basic.t pass. However, it fails on:

my $fact = $facter.fact($test-fact);
ok($fact, "test fact is loaded");

I was trying to add missing pieces but the module seems to be unfinished? I think the test file needs to set facter_perl6os=perl6os env var, or something like that. But I didn't manage to get it to chooch.

BTW I think PRs #3 #4 and #5 can be closed (no longer needed).

Any reason not to merge this? 😇
