    c++: lambda capture and shadowing [PR121553]

    P2036 says that this:

      [x=1]{ int x; }

    should be rejected, but with my P2036 we started giving an error
    for the attached testcase as well, breaking Dolphin.  So let's
    keep the error only for init-captures.

            PR c++/121553

            * name-lookup.cc (check_local_shadow): Check
!is_normal_capture_proxy.
