[PATCH v3 1/6] kexec: define KEXEC_UPDATE_ELFCOREHDR

[Eric DeVolder]

The Linux kernel defines this flag to indicate that the kexec_load()'ed
image is setup so that the kernel may directly modify the elfcorehdr
(and not cause the purgatory digest checksum to fail) in response to
CPU or memory hot un/plug and/or on/offline events.

Define this flag to match/mirror the kernel flag.
