Add a systemModules utility type
Storing system modules in a classpath is clumsy, as there should
only ever be one system modules, and it needs to store both a
directory to pass as the argument and a set of generated files
to use as dependencies. Store them in a separate systemModules
type instead.
Test: m checkbuild
