Try to make test 1963 pass on fugu
The fugu test device we use seems to be old enough not to have a real
memfd_create syscall and something about the setup (probably the
chroot) is preventing the tmpfile() fallback from working. To make the
bot green have the test check to see if memfd_create should work and
ignore the test results if it's not.
Test: ./test.py --host
Test: Hope
