DZ: use [Bootstrap::lib]

So we apply our code to ourself...
DZ: hard dependency on Test::CPAN::Changes

Using DZP::Test::CPAN::Changes without Test::CPAN::Changes being
installed is useless, and even gives a false sense of security.
So we add a hard install dependency on Test::CPAN::Changes. The
dependency is on the latest known version (0.19) to ensure that the
checks matters.
Inject develop dependency on Test::CPAN::Changes for 'dzil authordeps'

We have added install dependency for our distribution, but this is not
enough. We must ensure that the dependency is also available at runtime
for the contributors to the final distribution.
So the plugin injects a 'develop' dependency into the distribution the
plugin helps to build.
Hard dependency on Test::CPAN::Changes at runtime in the generated test

If the author choose to use this plugin, he is interested in its result.
So the test must not be skipped if Test::CPAN::Changes is missing
(whatever the reason) as it previously does. So we unconditionnaly load
the module, and a load failure is a failure of the test.
The test is in xt/release/ so we are sure that this change will only
affect the author, not the final user.
