FreeBSD's nullfs doesn't support file mount

FreeBSD doesn't have "bind" mount, but nullfs might be a similar feature.
However nullfs can mount only directories.

This adds a COPY command to docker build which works like ADD, but is
only for local files and it doesn't extract files.

Add ErrPrerequisites to improve misleading errors

There are two cases where we can't use a graphdriver:

1) the graphdriver itself isn't supported by the system
2) the graphdriver is supported by some configuration/prerequisites are
missing

This introduces a new error for the 2) case and uses it when trying to
run docker with btrfs backend on a non-btrfs filesystem.
