hotplug: install hotplugpath.sh as data file

rpmlint complains a script helper which is only sourced:

[ 1875s] xen-tools.i586: W: script-without-shebang /etc/xen/scripts/hotplugpath.sh
[ 1875s] This text file has executable bits set or is located in a path dedicated for
[ 1875s] executables, but lacks a shebang and cannot thus be executed.  If the file is
[ 1875s] meant to be an executable script, add the shebang, otherwise remove the
[ 1875s] executable bits or move the file elsewhere.
