Make views depend on Xext

Add a gyp target for Xext to linux/system so that Views can depend on it. A recent change added a code dependency within Views on linux on this library. Chrome was linking with it but other Views apps (candidate_window) weren't

I added a dependency on Xext for Views on linux (to support clicks passing
through status bubbles). This updates the views and linux system gyps so that
things other than chrome can link.

Can you make your commit description meaningful?  (Sorry to pick on you, but I
feel like 80% of the ChromeOS commits never describe why they're making the
change they're making.)  Like say perhaps which function or which change made
this necessary, etc.

I guess we already depend on libXext, so I'm a little surprised this is needed,
but it looks good otherwise.

$ ldd /opt/google/chrome/chrome | grep Xext
	libXext.so.6 => /usr/lib/libXext.so.6 (0x00007fc0aedc9000)

I'll do that, but the reason for the change is that the xext library dependency
is in Chrome, but the code dependency is in views. candidate_window needs to
pick up the change as well.
