Add boolean dependencies between plugin and provider subpackages

maven-surefire-plugin requires its providers to work correctly, yet it
doesn't have any dependencies on them -- it relies on maven-local to
pull in appropriate providers.

In order to make Java buildroots smaller, maven-local will no longer
require Surefire providers.  Instead, maven-surefire-plugin needs to
conditionally require its providers, depending on whether particular
testing framework package (JUnit, TestNG) is installed.
