- cat-file: add mailmap subcommand to --batch-command

The test suite harness and many individual test scripts have been
updated to work correctly when 'set -e' is in effect, which helps
detect misspelled test commands.
"git cat-file --batch" learns an in-line command "mailmap"
that lets the user toggle use of mailmap.
