core.5: Add info about DAX coredump filtering flags 

Kernel 4.4 added two new core dump filtering flags,
MMF_DUMP_DAX_PRIVATE and MMF_DUMP_DAX_SHARED.

These flags allow us to explicitly filter DAX mappings.
This is desirable because DAX mappings, like hugetlb
mappings, have the potential to be very large.
