Hello Tom,

you saw unreproducible results with multiple runs failing and one run
succeeding. The reason is that when signing with sign-efi-sig-list in
out Python tests without passing a timestamp two signatures may be in
the same second or not.

When using the signed files to set UEFI variables a variable can only be
overwritten by a file with a newer timestamp. But without setting
timestamps explicitly using parameter -t passed to sign-efi-sig-list we
have no control.

I already fixed this for some elder tests but missed to fix this for the
merged patches from Takahiro.

Best regards
