[Crash-utility] [PATCH v2 2/5] netdump: Permit --zero_excluded for incomplete ELF dumps

DUMP_ELF_INCOMPLETE is set very late after ENOSPC error is hit by makedumpfile. Any following error that prevents modification of ELF header would result in effectively incomplete core that doesn't have the flag. zero_excluded flag doesn't work for such kind of incomplete core.
