Include default msgmerge_options, adding --no-fuzzy-matching for custom makemessages command

[robdivincenzo]

Description

This will update the custom makemessages command to include default msgmerge_options as well as the --no-fuzzy-matching. As of 4.1, msgmerge uses the --update flag by default to update .po file: django/django@4bfe8c0

Unless there's a reason not to use them, including default options will help keep it stable going forward. Default options being included are now:

-q, --backup=none, --previous, --update

And for reference, here are the descriptions of the options: https://www.gnu.org/software/gettext/manual/html_node/msgmerge-Invocation.html

To test

1. Check out this branch
2. Run inv makemessages
3. Verify .po files in local l10n repo are now updating and that output is as expected

Also tagging @TheoChevalier for review since there are a few new default options being included with the custom command.
