Remove code that blocks mirrors of the Go source
Remove code that blocks mirrors of the Go source

The code was not updated to the new directory tree hierarchy described
in golang.org/s/go14nopkg.

The code blocked repositories that were not mirrors of the Go source
tree. See issue #184. Updating the code to the new directory hierarchy
will likely create more false positives.

The admin tool can be used to manually block a mirror.

Fixes #184.
