bootstrap: Remove unused ErrSocatNotFound

For RHELAH 7.5 we're dropping the `kubernetes` RPM which actually
indirectly dragged in `socat`.  There was some discussion about
this on atomic-devel@ a while ago:
https://lists.projectatomic.io/projectatomic-archives/atomic-devel/2015-March/msg00066.html

From some investigation, it looks like the kubelet now carries the code for
this.

And it turns out that this reference to socat was introduced by
2d58450 for something different (related to
Docker on OS X), but wasn't even used there.

Since I noticed it's unused, let's delete it. This patch reduces the number of
lines of Go code in this git repo by `0.000027%`.
