[LTP] [PATCH] lapi/syscalls: Add fallback definition for memfd_secret on arm

[Edward Liaw]

memfd_secret is not implemented on 32bit arm, but this change creates a
fallback definition so that it will return -1 and ENOSYS when calling
syscall(__NR_memfd_secret, 0).  This will allow tests such as accept03,
readahead01 and splice07 that use memfd_secret to skip with TCONF
