mm: page_owner: use kstrtobool() to parse bool option
I tried to use page_owner=1 for a while noticed too late it had no effect
as opposed to similar init_on_alloc=1 (these work).
Let's make them consistent.
The change decreses binary size slightly:
text data bss dec hex filename
12408 321 17 12746 31ca mm/page_owner.o.before
12320 321 17 12658 3172 mm/page_owner.o.after
