Bug#790302: perl-modules-5.22: libtest-tester-perl uninstallable

[Dominic Hargreaves]

Package: perl-modules-5.22
Version: 5.22.0-1
Severity: important
Affects: autopkgtest

During test rebuilds, I noticed (via autopkgtest, which uses apt-get
downloads on this module as part of the test suite) an odd effect with
libtest-tester-perl. This (and libtest-use-ok-perl) are now virtual
packages, as they have been folded into both perl and libtest-simple-perl.

This transcript shows the problem:

I think the solution is probably to have perl-modules-5.22
Provides libtest-tester-perl (et al) (in other words revert
5da2d5650164e49a400bec6c304f7e6bc0c98411) but I'd welcome other
thoughts.
