linux-kselftest-4.14-rc3-fixes 

This update consists of:
 
 - fixes to several existing tests
 - a test for regression introduced by
   b9470c2760 ("inet: kill smallest_size and smallest_port")
 - seccomp support for glibc 2.26 siginfo_t.h
 - fixes to kselftest framework and tests to run make O=dir use-case
 - fixes to silence unnecessary test output to de-clutter test results
