MAINTAINERS: update TUN/TAP maintainers

Willem and Jason have agreed to take over the maintainer
duties for TUN/TAP, thank you!

There's an existing entry for TUN/TAP which only covers
the user mode Linux implementation.
Since we haven't heard from Maxim on the list for almost
a decade, extend that entry and take it over, rather than
adding a new one.
