MacViews: Adjust linux_ui guards in process_singleton_posix to match views.gyp

MacViews: Adjust linux_ui guards in process_singleton_posix to match views.gyp

Currently a linux_ui.h #include/usage in process_singleton_posix is
guarded by toolkit_views && !chromeos which (along with _posix) will
include Mac.

views.gyp has
        }, { # OS=="linux" and chromeos==0
          'sources/': [
            ['exclude', 'linux_ui'],
          ],
        }],

so this just makes them match.

Hi sky, please take a look. (This CL might be TBR-worthy, but I thought I'd get
a second opinion on whether to keep `TOOLKIT_VIEWS`)

[sky, 2014-07-15 16:41:08]

I think we should keep the toolkit_views here.

LGTM

My rationale for this is that I think ozone may also be defined(OS_LINUX) &&
!defined(OS_CHROMEOS) but its not TOOLKIT_VIEWS.
