Update DEPS to always pull clang.

Update DEPS to always pull clang.

If the --if-needed argument is passed to the clang update script then we depend
on GYP_DEFINES to be set in order to update clang. We no longer define
GYP_DEFINES so we fail to update clang (or checkout clang).

PTAL.

Do I also need to update the pdfium recipe to add GYP_DEFINE=clang=1 back?

lgtm.

it looks like you only need clang=1 if you are using --if-needed.
