This is very specific to `jq` command. What's special with `jq` and not
others? If methods have to be shown, they should be shown for all the
programs which are not installed.

Further, this limits the information to specific package managers and
systems in the userspace. Tomorrow a new system may come, which will
cause this list to grow, not to mention other existing package managers.
The kernel also doesn't have a role in it, so we should try to be generic
as much as possible.

Thanks,
Siddh

Agree. The user could decide if jq should be install via REQUIRE_JQ. There are
also other cmds that vendor may not build by default. I didn't see any
selftests need to handle the installation. The users should takes care of it.

require_command() has takes care most of the needed cmds. If we want to
improve the user's experience for the needed cmds. I think add the needed cmds
to README file is better.
