Add tests to demonstrate what "mktag" does in the face of replaced
objects.
There was an existing test for replaced objects fed to "mktag" added
in cc400f50112 (mktag: call "check_sha1_signature" with the
replacement sha1, 2009-01-23), but that one only tests a
commit->commit mapping. Not a mapping to a different type as like
we're also testing for here. We could remove the "mktag" test in
t6050-replace.sh now if the created tag wasn't being used by a
subsequent "fsck" test.
