bhyve: Properly name bhyve help parsing function

Currently there's a function called bhyveProbeCapsRTC_UTC() that
parses bhyve capabilities from the bhyve help output (bhyve -h).
Right now it only checks the '-u' flag, but as there will be more
features detectable through this help output, give it more general
name: bhyveProbeCapsFromHelp().
