Subject: [PATCH] seccomp: arm64 does not have mmap2

I messed up when adding the definitions in 4278d1f5310f5acb4c6a6788233625234edb5145.
Unfortunately I didn't have the hardware at hand and went by
looking at the kernel headers.

(cherry picked from commit 79873bc850177050baa0c5165b119adafeebb891)
