    devtool: standard: Expand SRCREV before using it in _update_recipe_srcrev
    
    If SRCREV contains a variable reference, any devtool command that
    would try to update it would fail. E.g., if SRCREV = "R${PV}", then
    devtool finish without having committed any changes would fail with:
    
      oe.patch.CmdError: Command Error: 'sh -c 'git format-patch R${PV} -o
      /tmp/oepatchb_doareb -- .'' exited with 0 Output:
      fatal: bad revision 'R'
