HostUnitTestCompilerPlugin: enable single module build test execution (…

…#219)

Updates the HostUnitTestCompilerPlugin to skip post build
scripts in all scenarios, then find and execute only plugins with the
host-based-test scope. This enables the HostUnitTestCompilerPlugin
to successfully execute and log host-based unit tests for single
module builds and for normal builds.
