gpMgmt: Update `make` cleanup for gpMgmt directory

When a user runs a `make distclean`, we actually don't cleanup the gpMgmt
directory. This change fixes this issue.

Make the clean more verbose. It's hard to tell what happened without any
feedback from the commands.

Update the clean/distclean to remove pythonSrc/*/build directories as well.
