t1006: don't strip timestamps from expected results

In t1006 we have a bunch of tests that verify the output format of the
git-cat-file(1) command. But while part of the output for some tests
would include commit timestamps, we don't verify those but instead strip
them before comparing expected with actual results. This is done by the
function `maybe_remove_timestamp`, which goes all the way back to the
ancient commit b335d3f (Add tests for git cat-file, 2008-04-23).

Our tests had been in a different shape back then. Most importantly we
didn't yet have the infrastructure to create objects with deterministic
timestamps. Nowadays we do though, and thus there is no reason anymore
to strip the timestamps.

Refactor the tests to not strip the timestamp anymore.
