Further developement of the (if any) will happen in the git branch
"xen-tools-moose" where they are still available.
Also remove the according (already disabled) tests and test
modifications from the test suite.
Also remove no the more needed build-dependency on Moose as well as
one Makefile line installing the above mentioned Perl modules.
done_testing appeared in Test::More 0.87, which is not in perl 5.10,
and therefore not in debian stable.
This makes t/perl-syntax.t pass on debian stable and causes no more
trouble.
