Subject: [PATCH 11/26] kernel/vmcore_info: Register dynamic information into meminspect

Register vmcoreinfo information into inspection table.
Because the size of the info is computed after all entries are being
added, there is no point in registering the whole page, rather, call
the inspection registration once everything is in place with the right size.
A second reason is that the vmcoreinfo is added as a region inside
the ELF coreimage note, there is no point in having blank space at the end.
