Ævar Arnfjörð Bjarmason 06ce79152b mktag: add a --[no-]strict option
Now that mktag has been migrated to use the fsck machinery to check
its input, it makes sense to teach it to run in the equivalent of "git
fsck"'s default mode.

For cases where mktag is used to (re)create a tag object using data
from an existing and malformed tag object, the validation may
optionally have to be loosened. Teach the command to take the
"--[no-]strict" option to do so.
