Fix warning caused by unused-result in bug-atexit3-lib.cc
The test case dlfcn/bug-atexit3-lib.cc calls write and doesn't check the result. When building with GCC 6.2, this generates a warning in 'make check', which is treated as an error. This patch replaces the call to write with a call to write_message. Tested for powerpc64le.
