[PATCH v2] Fix install.sh for systemd

[Olaf Hering <olaf@xxxxxxxxx>]

On a fedora system, if you run `sudo sh install.sh` you break your
system.  The installation clobbers /var/run, a symlink to /run.  A
subsequent boot fails when /var/run and /run are different since
accesses through /var/run can't find items that now only exist in /run
and vice-versa.

Skip populating /var/run/xen during make install.
The directory is already created by some scripts. Adjust all remaining
scripts to create XEN_RUN_DIR at runtime.

XEN_RUN_STORED is covered by XEN_RUN_DIR because xenstored is usually
started afterwards.
