Enable chrome.gyp:browser_ui on iOS

Enable chrome.gyp:browser_ui on iOS

Re-enabled building of the browser_ui target on iOS (lost when
unit_tests was turned down). As with browser, removes non_android
sources and puts everything in non_mobile_sources.

Yeah, I went back and forth on this. It's plausible that there could be
!ChromeOS sources that would apply on iOS, and it's just that these two don't
(which is why I didn't make the variable expansion the thing that populates
sources!). And for two sources, it didn't seem worth trying to rejigger to make
a not_chromeos_or_ios and then potentially have this section come back later.

Hopefully iOS using browser_ui will be unwound before those lists grow enough
that it becomes an issue.
