[CPAPNLUS::Dist::Build] Up dependency version of Module::Build

[Jos Boumans]

Greetings,

I've just commited the following patch on C::D::Build [#2734], which
probably warrants a new release:

  * up dependency to 0.28 of Module::Build, since we use
    Module::Build->_mb_feature('C_support') in our tests

Clients that have a version of M::B installed of pre 0.28 will see their
test suite fail on the
current C::D::Build.
