Update post build script when replacing MMAC certs.

The sign_target_files_apks script will add an extra
MMAC file when replacing the certs. This update will
ensure that only one MMAC file is left in the zip
file.

When the OTA zip is created by the follow-on
ota_from_target_files script the extra file would
override the original as expected. And thus the
correct MMAC file(s) were being used. This patch
just ensures that the intermediate script produces
an unambiguous zip file.
