fix: replace `/var/run` by `/run`

The use of `/var/run` was deprecated by FHS 3.0 nine years ago, so it's
time to finally get rid of it where possible. The canonical directory
for run-time variable data is `/run` nowadaya,s with `/var/run` just
being a symbolic link for backward compatibilty and to ease transition.
