[OE-core] [PATCH V3 1/5] systemd: add 'less' to its RRECOMMENDS

[Chen Qi]

The less command provided by busybox cannot interpret the control
character, resulting in obscure output of the journalctl command
in a systemd based image.

Add the 'less' package to systemd's RRECOMMENDS so that the output
of 'journalctl' looks clear to users.
