checkpkg: add option to avoid keeping the tmp dir

In some cases, like default makechrootpkg execution, the temporary
directory used to assemble the differences is not required. Add an
option to checkpkg that allows to get rid of that directory after
run and call it automatically like that in makechrootpkg.
