Bug/cctools syscall (#4440)
* Handle missing defn of __NR_memfd_create
Generally SYS_foo is defined to __NR_foo (in sys/syscall.h) which is
then defined to a syscall number (in asm/unistd_64.h). Certain CentOS
systems have SYS_memfd_create defined to __NR_memfd_create but are
missing the second definition. This is a belt and suspenders solution
to the problem.
See [this post][syscall] for a nice general description of how these
parts fit together.

* Avoid flake8 warning
