libpayload: update junit.xml target, clean up output

- Copy each config in configs/ to the junit_config, update each,
    in turn, and clean up when done.  This avoids updating the saved
    config files and creating dirty files in git.
    - Use 'make olddefconfig' instead of 'yes "" | make oldconfig'
    - Update clean target to remove junit_config file
    - Update distclean target to remove junit.xml
