There is an effort in progress to generate a QEMU Python
package. As I'm not sure this old email is still valid,
update it to not produce package with broken maintainer
email.
Patch created mechanically by running:
$ sed -i 's,\(__email__ *= "\)stefanha@linux.vnet.ibm.com",\1stefanha@redhat.com",' \
$(git grep -l 'email.*stefanha@linux.vnet.ibm.com')
