pkg: systemd: add initial MAINTAINERS

I volunteered for pkg/systemd MAINTAINER and there were no objections
during the #docker-dev meeting. For context I wrote most of the stuff in
here and wrote the dependent calls in api.go. Plus, I actively test the
code via CoreOS.

devmapper: Enable skip_block_zeroing

This makes the device mapper not zero out blocks allocated on the
thinp device. This is safe in our use case, as we access the device
via a filesystem that doesn't leak any uninitialized data to userspace.

This partially helps with https://github.com/dotcloud/docker/issues/3280
and should generally improve preformance on the devicemapper backend.

Add slightly better GOPATH detection/handling

This also adds a new "AUTO_GOPATH" environment variable that will create an appropriate GOPATH as part of the build process.
