nutdrv_qx: clean up the CLI usage/help message

[jimklimov]

Currently it seems the umbrella driver just posts all addvar items there are from the built-in subdrivers. It makes sense to either de-duplicate them, or clarify which configuration key words are "global", and which are defined by a particular driver by just adding a banner between subdriver lists of values.

The clumsy output seen today is:

...
Acceptable values for -x or ups.conf in this driver:

Set shutdown delay, in seconds (default=30) : -x offdelay=<value>

Note: recent changes to upsdrv_help() in #2058 are NOT the solution to this issue ;)
