[Buildroot] [PATCH 4/4] package/lttng-{libust, tools}: use proper systemd rundir

[Norbert Lange <nolange79@gmail.com>]

Set the rundir to /run/lttng, if systemd is the init system.
/var/run is "legacy" in systemd's view.

Perhaps a better way would be to define a variable
BR2_PACKAGE_RUNDIR to /var/run or /run depending on ini system.
(systemd will for example issue warnings for the dbus service,
using a socket in /var/run)
