Check harder whether file is really under WORKDIR
1977b57bc9aaea71252358fa502110c348153c70 "vcl: loplugin:override" had only hit
in out-of-tree builds, where the #include in the generated
workdir/CustomTarget/vcl/unx/kde4/tst_exclude_socket_notifiers.moc is an
absolute path. For in-tree builds, the generated #include line is
"../../../../../vcl/unx/kde4/tst_exclude_socket_notifiers.hxx", so the returned
getFileName() is .../workdir/../../../../../vcl/..., so was erroneously
considered to be under WORKDIR.
