Prevent name conflict for eventfd.cpp and eventfd.s when building libc.a

 - eventfd.cpp and eventfd.s will output to the same file when building libc.a
   out/target/product/*/obj/STATIC_LIBRARIES/libc_intermediates/WHOLE/libc_common_objs/eventfd.o
 - And then `eventfd` will undefined when statically linked to libc.

Also add a unit test.
