git-fsck: report missing author/commit line in a commit as an error

A zero commit date could be caused by:
* a missing author line
* a missing commiter line
* a malformed email address in the commiter line
* a malformed commit date

Simply reporting it as zero commit date is missleading.

Additionally, it upgrades the message to an error (instead of an printf).
