Title:
sync_file_range fails in nspawn containers on arm, ppc

Bug description:
[impact]
calling the glibc function sync_file_range() on a armhf nspawn
container fails.
[test case]
see sample C program from original description below. compile and run
that inside a nspawn container on armhf and it will fail.
nspawn instructions:
sudo apt install debootstrap systemd-container
sudo -i
debootstrap --arch=armhf bionic ~/bionic-tree/
systemd-nspawn -D ~/bionic-tree/
[regression potential]
this only adjusts nspawn to allow the sync_file_range2 syscall which
is used on armhf, so the regression potential is very low. any
possible regressions would likely be when calling sync_file_range().
[other info]
original description:
---
ARM has two sync_file_range syscalls, sync_file_range and
sync_file_range2. The former is apparently not used, and glibc calls
the latter whenever a userspace program calls sync_file_range. I'm
guessing systemd-nspawn doesn't know this, because the follow code
consistently fails in an nspawn container on ARM:
#define _GNU_SOURCE
#include <fcntl.h>
#include <unistd.h>
#include <stdio.h>
#include <errno.h>
void main()
{
int f = open("/tmp/syncrange.test",O_CREAT|O_RDWR,0666);
int r=sync_file_range(f, 0, 0, 0);
if (r)
perror("sync_file_range");
close(f);
}
This seems to be causing problems specifically for borg(backup) and
postgres:

The solution should be to cherrypick
https://github.com/systemd/systemd/pull/13352, I am currently waiting
for systemd to rebuild on a slow ARM box. Any chance of an SRU?
