HWPOISON: Add PROC_FS dependency to hwpoison injector v2

Browse Source 
The injector filter requires stable_page_flags() which is supplied
by procfs. So make it dependent on that.

Also add ifdefs around the filter code in memory-failure.c so that
when the filter is disabled due to missing dependencies the whole
code still builds.
