Update the test suite to reflect libfile-temp-perl removal

libfile-temp-perl is not currently in Debian unstable, so
refreshing data/fields/perl-provides causes a test failure.
Use libthreads-shared-perl instead in the hope it will stay
separately packaged.

Improve the version information of packages bundled with the Perl core

There are various incompatibilities with the CPAN and Debian versioning
schemes. Try to be smarter about deriving Debian version numbers from
Module::CoreList data, taking epochs and varying number of decimal digits
into account.

Most of this code is reused from the Debian maintainer tests of the
Perl package (debian/t/control.t in the 'perl' source package, 5.14.2-21
or so at the time of this writing.)

Refreshed perl-provides with the improved versioning logic

Signed-off-by: Niels Thykier <niels@thykier.net>
Augment the test suite for the improved perl-provides logic

libmodule-build-perl in squeeze was 0.360700, but the old versioning
logic erroneously compared against 0.3607, resulting in a false
negative.
