Create aliases for generating RPM and DEB sdist

Adds the following aliases to assist with packaging-specific sdist.
 * dev_deb and release_deb - includes only .pyc files
 * dev_rpm and release_rpm - includes only .py files (later removed by
   install_lib)

The rpm sdist tarball is a traditional source distribution.  During the build
process, RPM will byte-compile and remove the .py source files.  The deb sdist
includes only byte-compiled awx python.
