fixups to init script rework

fixups to init script rework

- move action() from common to sysvinit wrapper since its only really
  applicable for sysvinit and not the other init systems

- fix bug in action() fallback, need to shift away msg before executing action

- make lxc-net 98 so it starts before lxc-container (99), otherwise the lxcbr0
  won't be available when containers are autostarted

- make the default RUNTIME_PATH be /var/run instead of /run. On older
  distros (like ol6.5) /run doesn't exist. lxc-net will create this directory
  and attempt to create the dnsmasq.pid file in it, but this will fail when
  SELinux is enabled because the directory will have the default_t type.
  Newer systems have /var/run symlinked to /run so you get to the same place
  in that case.

- add %postun to remove lxc-dnsmasq user when pkgs are removed

- fix bug in lxc-oracle template that was creating /var/lock/subsys/lxc as
  a dir and interfering with the init scripts
