dgit: Do not fail when run with detached HEAD. Closes:#853022.
Specifically: * Pass -q to git-symbolic-ref. That means that it doesn't print an error message when HEAD is not a symbolic ref (ie, a detached head), and it means that the exit status is then 1 rather than 128. * If the return value from cmdoutput_errok is undef, check $? (which is the exit status <<8) and then simply pass on the undef. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
