Allow arbitrary read-only shared pfn-remapping too
The VM layer (for historical reasons) turns a read-only shared mmap into
a private-like mapping with the VM_MAYWRITE bit clear. Thus checking
just VM_SHARED isn't actually sufficient.
So use a trivial helper function for the cases where we wanted to inquire
if a mapping was COW-like or not.
Moo!
