Move checkbuild targets of Soong modules into Soong

Let Soong specify the files that will be built by checkbuild for
each Soong module.  This will give better control over which files
get built, allowing checkbuild to skip the jar combining step when
transitive classpath jars are enabled.

Test: m checkbuild
