Add CONFIG_USER_NS and CONFIG_PID_NS to needs_kconfigs so these tests return TCONF instead of failing.

With the loop runs, those regions accumulate consuming both virtual address space and committed physical memory right away instead of lazily. Easily mmap() fails with ENOMEM on smaller/limit RAM resource system. Error Log: cve-2017-17052.c:48: TBROK: mmap((nil),16777216,PROT_READ(1),32802,-1,0) failed: ENOMEM (12) tst_test.c:479: TINFO: Child process reported TBROK killing the test tst_test.c:1909: TINFO: Killed the leftover descendant processes Consider there is no practical upper bound on this allocation pattern, so setting .min_mem_avail may not helps. Here we just tolerate ENOMEM during the mmap_thread() looping.
