[PATCH v2 0/2] add sysfs entry "patched" for each klp_object

I was debugging an issue that a livepatch appears to be attached, but
actually not. It turns out that there is a mismatch in module name
(abc-xyz vs. abc_xyz), klp_find_object_module failed to find the module.

Changes v1 => v2:
1. Add selftest. (Petr Mladek)
2. Update documentation. (Petr Mladek)
3. Use sysfs_emit. (Petr Mladek)
