Hide non-standard syslog API.
The definitions are still available on LP32 for binary compatibility, but they're gone on LP64, and the declarations are gone everywhere. We should probably just make syslog(3) log to the regular Android log, but that's a job for another day. Bug: 11156955 Change-Id: I74a98c92f7922ea733549ec6d37c6fa8b7014860
