url2pkg: remove interactivity

In the first phase, url2pkg generates a minimal package Makefile, barely
enough for downloading the distfile from the given URL.  That part runs
fully automated in almost all cases, so there is no need to invoke the
editor at this point.

After adjusting the package Makefile based on the downloaded and
extracted distfile, url2pkg has done its job, so there is no reason to
run the editor there as well.

Bump version.
