[PATCH] package_deb/package_ipk: Cleanup control file handling/races

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If you Ctrl+C ppackage_write_{deb/ipk} control files can get left lying around
and make it into another packaging format. This ensures we cleanup all known
control files before starting packaging. We can simplify some of the globbing
as a result.
