+1. Spec conditionals tend to hurt my brain :)

Hello, Whether the perl/perl-devel split in devel (#226276) is here to stay or not, I'd like to make the attached change to the rpmdevtools perl spec template. Using perl(ExtUtils::MakeMaker) as the "base" build dependency is correct in the vast majority of cases, no matter in which package ExtUtils::MakeMaker is included. Packages using Module::Build should change the dep to perl(Module::Build) - that'll pull in ExtUtils::MakeMaker too in case it's needed for Module::Build's non-compat mode. Doing the build dep this way should work for all distro versions as-is without the need to put ugly conditionals on whether to pull in perl-devel or not or whatever other perl package reorganizations we might see in the future. I see some packagers have already started to make those unnecessary specfile complications/per-distro forks so it'd be good to have this in the spec template as well as applicable Wiki pages as soon as possible. Comments, objections?
