t1006: stop using 0-padded timestamps
The fake objects in t1006 use dummy timestamps like "
0000000000 +0000".
While this does make them look more like normal timestamps (which,
unless it is 1970, have many digits), it actually violates our fsck
checks, which complain about zero-padded timestamps.
This doesn't currently break anything, but let's future-proof our tests
against a version of hash-object which is a little more careful about
its input. We don't actually care about the exact values here (and in
fact, the helper functions in this script end up removing the timestamps
anyway, so we don't even have to adjust other parts of the tests).
