Revert "SimpleChrome: Update GN args to make LLD default linker for Chrome."

This reverts commit fa5cbe8e521f3c878983954159afad12a1f6e61a.

Reason for revert: Seems to be causing bad images in Chrome OS using
simple-chrome-built images  (see
https://bugs.chromium.org/p/chromium/issues/detail?id=917504).

Original change's description:
> SimpleChrome: Update GN args to make LLD default linker for Chrome.
>
> LLD has been the default linker for Chrome in Chrome OS for
> nearly two weeks.  It is blocked from automatically becoming the
> default linker in Simple Chrome by crosbug/913317.  This forces
> LLD to be the linker for Chrome, until that bug can be fixed.
>
> BUG=chromium:862442
> TEST=LLD has been used for building Chrome in Chrome OS for two
> weeks.
