Geoffrey Thomas a8dbb92b47 Fix build on Android API levels below 21
signal(), sigemptyset(), and sigaddset() are only available as inline
functions until Android API 21. liblibc already handles signal()
appropriately, so drop it from c.rs; translate sigemptyset() and
sigaddset() (which is only used in a test) by hand from the C inlines.

We probably want to revert this commit when we bump Android API level.
