dmioem: Fix segmentation fault in dmi_hp_240_attr()

pr_attr() does not accept a NULL format string. glibc can deal with
it, but FreeBSD's libc chokes on it.

Display the attributes as a list instead. Pack the attribute name and
status into a single formatted string that can be passed to
pr_list_item(). That's arguably a hack, but it's cheap, non-intrusive,
and works nicely in the end.

Bug reported by Scott Benesh (Microchip).
