Passing ownership of mingetty

[Bernie Innocenti]

Hello Petr,

I ended up being the owner of mingetty by chance, because I used to
maintain it in the OLPC collection and the previous maintainer released
the package.

Since you're clearly working on it, I think it would make sense to pass
ownership to you. If you agree, I will orphan the package so you can
take it over (there doesn't seem a way to do a direct transfer in
pkgdb).
