devel/scons: Upgrade 2.3.0 => 2.4.1 and reset maintainer

While the maintainer has mostly been responsive since July 2010, his
actions were limited to approving PRs (mainly to upgrade scons because
the maintainer wasn't doing it). Not a single update originated from
the maintainer himself. Since being a gatekeeper isn't the purpose of
a maintainer, I'm going to reset the port on this timeout so that future
upgrades can get applied faster than they have been.
