43617: vcs_info git: During a non-interactive rebase of a detached head, computer the %b expando correctly.

Browse source 
Before this commit, the value of %b was the hash of the commit from the
"source" side of the rebase, from .git/rebase-apply/orig-head and
.git/rebase-apply/original-commit.  This broke the invariant that
%b expands to a git-rev-parse(1) expression resolving to what %r
expands to.

Use .git/rebase-apply/onto instead as, empirically, it contains the
correct value.
