Add GYP variable for disabling sanitizer_options.

In https://codereview.chromium.org/238123003 an import
of base.gyp is introduced in build/common.gypi. This
makes GYP fail for some client projects using the Chromium
build toolchain. By adding a condition variable for this
part, it is possible to avoid this include by setting
use_sanitizer_options=0.

NOTRY=True
BUG=302040
TEST=passing runhooks on a variety of trybots.
