QPID-4526: stop deleting (and logging that we are) the scratch profile properties file so that it then gets (re)created, just use force the concatenation without appending, i.e overwrite.

QPID-4527: update the JCA module to use the standard build target implementation, rather than replacing it.

- Overrides the output destinations (to give the filenames 'ra' instead of 'jca' as it was doing) and uses the postbuild target to additionally create the rar and examples.
- Moves the META-INF resources for the rar file to their own directory, removing need to specifically prevent their inclusion in the jar file.
