CPack: Enable DEB and RPM tests more reliably

CPack DEB and RPM generators were not used for some tests because
CPACK_BINARY_DEB and CPACK_BINARY_RPM variable were not set.  Fix this,
simplify generator selection in CTEST_RUN_CPackComponentsForAll, and fix
bugs that were detected after tests were run.
