[PATCH 1/2] peel_ref: rename "sha1" argument to "peeled"

[Jeff King <peff@peff.net>]

The "sha1" argument of peel_ref is meant to hold the peeled
object name for output. Let's call it "peeled" which makes
it more clear that it is not an input sha1 (especially as we
will be adding such an input sha1 in the next patch).

Simple cleanup for the next step.
