Fix superfluous v in s6-overlay versioning

[lmagyar]

Proposed Changes

In PR #217 (note the character v)

-ARG S6_OVERLAY_VERSION="3.1.4.0"
+ARG S6_OVERLAY_VERSION="v3.1.4.0"

But this hasn't changed:

COPY s6-overlay /package/admin/s6-overlay-${S6_OVERLAY_VERSION}/

No we've got this:

$ls -liag /package/admin/s6-overlay-3.1.4.1/etc/s6-rc/scripts/
 407304 drwxr-xr-x    2 root          4096 Mar 15 17:12 .

This modification is not tested!!! But can't think of any other cause for this issue.
