Ignore viewport meta tags when Request Desktop Site is enabled.
This matches desktop Chrome, and it applies the default
"min-width: 980px;" in viewportAndroid.css -- putting responsive
pages into their desktop/tablet layout.
The enableViewport/enableMetaViewport settings distinction had
bit-rotted somewhat since they've always been the same value
(in fact disabling the latter setting didn't actually drop support
for it) so I needed to do some cleanup there as well.
