memfd_create: disable for ANDROID_API < 30

The syscall is wrapped in Bionic from API version 30:
  https://android.googlesource.com/platform/bionic.git/+/3d24d2b0883e%5E!/

This fixes the build for earlier versions of Android. Note that
MDF_CLOEXEC as well as the raw syscall numbers for memfd_create
were added much earlier:
