Don't reference instrumented-libraryes with sanitizers disabled.

Don't reference instrumented-libraryes with sanitizers disabled.

Previously //build/config/sanitizer:deps unconditionally depended on
//third_party/instrumented_libraries:deps. This dependency is only necessary
//when compiling with a sanitizer, and in standalone other projects like nacl,
//instrumented_libraries doesn't exist.

This patch makes all contents of sanitizer:deps conditional on using a
sanitizer, which matches what the documentation explicitly says.

Scott: I think you originally set this up. Do you know why it used to work the
way it did? I think this new way should be correct.

I did originally do build/config/sanitizers/BUILD.gn, but the line you're
changing was added here: https://codereview.chromium.org/1150193002 by sammc.
Not sure why he made it unconditional.

LGTM
