PackageMaker: Enable postflight script in component mode (#12375)

Previously, setting CPACK_POSTFLIGHT_SCRIPT had no effect in
component mode, when CPACK_COMPONENTS_ALL was set.

In component mode, a .mpkg is created that contains multiple .pkg's.
Because postflight scripts only work in a .pkg, add another .pkg to the
.mpkg and put the postflight script in that.
This is the same approach taken by the PackageMaker GUI when adding
a postflight script to a metapackage.
