Bug 33060: Fix yes/no setting to 1/0 in system preference YAML files

Boolean system preferences need to use 1 and 0 for true and false,
not yes and no now. This fixes a few occurences that have
been added in the last release:

* EnableItemGroups
* EnableItemGroupHolds
* ArticleRequestsOpacHostRedirection
* UseLocationAsAQInSIP

To test:
* Make sure these preferences save to the db as 0/1 as expected.
