bsdinstall(8) services: Set moused_nondefault_enable

[asiciliano]

Summary

PR: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227999
Reported by @bcran :

bsdinstall(8) has an option to enable moused support. However, if it's _not_ selected, moused is still started through the configuration of nondefault devices. It might be nice to either have another option to disable nondefault devices, or have bsdinstall automatically add the moused_nondefault_enable="NO" setting to rc.conf unless moused support is selected.

@bcran I added "automatically add the moused_nondefault_enable="NO" setting to rc.conf unless moused support is selected", or do you prefer "another option to disable nondefault devices"? If you want a new option, what should be the name and description?

Test Plan
