I wonder if this is actually necessary in this case? But it does make it
consistent with the "Chrome" case.

Please add some sort of comment indicating that this causes the binary to be in
PRODUCT_DIR instead of lib/.
(For Clear Key, we say "# Must be in PRODUCT_DIR for ASAN bot." I don't know if
that's strictly true in this case.)

Done.
