[GRUB PATCH 1/2] 20_linux_xen: Ignore xenpolicy and config files too



"file_is_not_sym" currently only checks for xen-syms.  Extend it to
disregard xenpolicy (XSM policy files) and files ending .config (which
are built by the Xen upstream build system in some configurations and
can therefore end up in /boot).

Rename the function accordingly, to "file_is_not_xen_garbage".
