sysutils/mkr: add port: Command line tool for Mackerel

mkr is a command-line interface tool for the Mackerel API written in
Go. mkr helps to automate tedious daily server operations to best
leverage Mackerel's and Unix's tools. mkr output format is JSON, so it
can be filtered with a JSON processor such as jq.
