Subject: [PATCH] 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.
