mem: add extra mem pages for pthread stack
Some archs can use even 64K pages and then lvm2 runs into trouble if
the stack is 'too small' to fit extra page capturing stack overwrite.
So when lvm2 limits stack - add extra mem page - be it 4K or 64K.
Relates to ppc64le bug: https://bugzilla.redhat.com/1387279
