Fix mac_views_browser compile after r435575 (extension_uninstall_dialog_view_browsertest.cc)

go/macviewsbuilder broke after r435575. It removed a flag that
extension_uninstall_dialog_view_browsertest.cc was using.

But extension_uninstall_dialog_view_browsertest.cc is only built on
mac_views_browser builds, which doesn't need flags in the first place
(it's a compile/build flag).

One of the tests does sadly fail (see http://crbug.com/671098), but
that's because it depends on things that should be gone by the time
mac_views_browser is a thing.

BUG=425229, 671098
