Mikhail Zaslonko 6d15850480 zdump: Use os_info data to convert dump vaddr to paddr ...

For vr-kernel dumps use the offsets stored in os_info entries for
virt to phys address conversion when dump virtual address is to be
read, (e.g. vmcoreinfo symbols) using similar method as implemented
in crash-utility.
It is mainly required for reading "init_uts_ns" symbol and, in case
of crashed kdump, "lowcore_ptr" symbol along with a pointers to the
lowcore of every CPU.
