[CRIU] [PATCH] build: memfd -- Use SYS_memfd_create for libc sake

[Cyrill Gorcunov]

Just got a situation inside VM where pretty new
kernel with memfd has been installed (and as result
__NR_memfd_create shipped with kernel headers
is provided as well) but libc was old having no
SYS_memfd_create defined. Thus we've got an error
because we use exactly SYS_ number for calls.
