Hi guys, I need your LGTM again. 

The last CL (https://codereview.chromium.org/398823004) got reverted because it
broke Linux GN bot.

This is the same CL + fix to media BUILD.gn file. I tested locally and it
worked. Plus I am added the linux_gn_rel to try bot list here.

Good luck this time!

pro-tip: You could upload the original CL first, then upload the fix, so that
people can see what's the fix more easily.

LGTM
