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.

(cherry-pick of 8baa929d5d3bcf63381cf78ba76168c80c303f5e.)
