[Patch] GenBiosId: Enable GenBiosId to set timestamp as zero

["Bob Feng" <bob.c.feng@intel.com>]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2384

We need eliminate the effect of timestamp to verify
the reproducible build.

This patch is to add the support for GenBiosId to set
timestamp as zero.
