Your Kernel 3.10 is too old for systemd IFF using systemd-v230 or newer.
According to systemd kernel requirements in github at (github.com - systemd README) you need version >= 3.12 if you are using systemd-v230 or newer:
REQUIREMENTS:
Linux kernel >= 3.12
Linux kernel >= 4.2 for unified cgroup hierarchy support
Lines 37, 38 and 39 are printed above.
You are running under ARM architecture which I frankly know little about. Google search tells me your armvl7 is used by Raspberry Pi and is a 32 bit kernel.
Updating your Kernel to modern times
If you want the latest (October 21, 2016) “Dirty COW” security protection (What is the "Dirty COW" bug, and how can I secure my system against it?) plus a host of other security patches, bug fixes and system improvements (after your 2013 version) you should be on kernel 4.4.0-47.
Unfortunately I don’t know how to do that for a RaspberryPi. I have linked this question to people who use RaspberryPi and have asked them to critique this answer.
