Always define ABSL_ALLOCATOR_NOTHROW=1.

From absl/memory/memory.h:
// ABSL_ALLOCATOR_NOTHROW is a build time configuration macro for user to
// specify whether the default allocation function can throw or never throws.
// If the allocation function never throws, user should define it to a non-zero
// value (e.g. via `-DABSL_ALLOCATOR_NOTHROW`).
// If the allocation function can throw, user should leave it undefined or
// define it to zero.

Since exceptions are not allowed in Chromium, it is probably safe to assume
the default allocation function also never throws.
