[jhbuild] [git] don't capture stderr when running git rev-parse

commit b5a1f42c7d0bc33deb8fcf7191dadf87a966d142

    [git] don't capture stderr when running git rev-parse
    
    This is to avoid git messages about ambiguous refnames, when HEAD
    is also a tag name (such as it happens with ORBit2).
