Issue #324 - Follow-up: Remove more traces of *INTL_API.

The trace in Spidermonkey's old-configure is causing the MOZ_CONFIG_ICU function
to be called twice, which is not desirable as it can cause the MOZ_SHARED_ICU
check in build/autoconf/icu.m4 to fail and build an ICU data file even if we're
building ICU as a shared library.
