logtoprocess: sends the canonical command name to the subprocess

One of the use-case of logtoprocess is to monitor command duration. With the
current code, we only get whatever command name the user typed (either
abbreviated or aliased).

This makes analytics on the collected data more difficult. Stores the
canonical command name in the request object. Pass the stored canonical name
in the `req.ui.log("commandfinish", ...)` call as keyword argument to not
break potential string formatting.

Pass the value as the environment variable named `LTP_COMMAND` to the called
script.
