Refactor: tools: Drop only known use of "cibadmin -!"

Replace it with pacemakerd -F, whose output is very similar and
includes the feature set.

Nothing in resource-agents or pcs appears to use this option.
report.collector doesn't work when called directly, so we can assume
it's being called by crm_report. I don't see any reason why anything
would depend on the exact format of the output. If someone complains, we
can revisit.
