sed-native: drop

sed-native: drop

This was added back in the depths of history (around 2006 in OE-Classic)
when apparently the host sed couldn't always be relied upon. We now call
the host sed all over the place without this dependency and don't have
any problems. On the other hand, having it around can lead to races
where we're calling sed in one task and staging it to the sysroot in
another, the result being nasty failures compiling binutils for example.
Since it isn't needed, let's just drop it completely.

Fixes [YOCTO #7264].
