Revert of Reenable linux_aura on the main builders. (https://codereview.chromium.org/136813004/)

Reason for revert:
Failed due to mysterious failures on the Google Chrome Linux bot.

Example:
FAILED: cd ../../chrome; flock -- /tmp/linux_package_lock bash ../out/Release/installer/debian/build.sh -o../out/Release -b ../out/Release -a ia32 -c stable

BUG=335451

Original issue's description:
> Reenable linux_aura on the main builders.
> 
> We fixed the browser test slowdown that lead to linux_aura being
> disabled in r235280. (Different test suites are faster or slower, but
> overall, tests run faster.)
> 
> We are turning this on primarily to get perf data; if things look
> acceptable, we hope to cut a dev channel this week.
> 
> BUG=319075,125106,303342,318961
> NOTRY=True

> Committed: https://src.chromium.org/viewvc/chrome?view=rev&revision=245415
