hotplug/Linux: install sysconfig files as data files

rpmlint complains about wrong permissions of config files:

[  455s] xen-tools.i586: W: script-without-shebang /var/adm/fillup-templates/sysconfig.xendomains
[  455s] xen-tools.i586: W: script-without-shebang /var/adm/fillup-templates/sysconfig.xencommons
[  455s] This text file has executable bits set or is located in a path dedicated for
[  455s] executables, but lacks a shebang and cannot thus be executed.  If the file is
[  455s] meant to be an executable script, add the shebang, otherwise remove the
[  455s] executable bits or move the file elsewhere.
