Fix en_GB's language name failure

Fix en_GB's language name failure

data/lang/en_GB.txt has an empty "Languages" block leading
getDisplay{Name,Language} to fail in en-GB.

Update trim_data.sh to remove an empty "Languages" block and run the
script to fix data/lang/en_GB.txt and other locales if any. (only
en_GB.txt is affected).

Rebuild the icu data with the above changes for both Android and non-Android
platforms.

PTAL, thanks. 

This should be the last CL before actually rolling DEPS to 54.1.

I think you sent this to the wrong Mark.

V8 doesn't compile anymore with clang after this change:
https://codereview.chromium.org/945703002/

Is there anything wrong on our side? I'll try to repro this locally.

Looks like the incremental build gets stuck only. It works on a clobbered build.
I'll try to land the deps changes with a landmine.

Thanks for taking care of this v8 issue as well as quickly picking up the ICU
DEPS roll in v8. 
Let me know if you need me wrt icu in v8.
