releasetools: Use fixed timestamp in otacerts.zip. 

We were using zipfile.write() to write system/etc/security/otacerts.zip
when signing for release. It led to unexpected timestamp change in the
generated otacerts.zip and non-idempotent signed images when signing the
same target_files.zip.

Replace with common.ZipWrite() to always use a fixed timestamp.
