[RFC] remove dead code from link_elf.c

[Oliver Pinter]

Hi all!

I found that the SPARSE_MAPPING used only in sys/kern/link_elf.c file,
and no other place in kernel, nor in generated codes in /usr/obj/...

op at pandora-d opBSD.git> git grep -i SPARSE_MAPPING
sys/kern/link_elf.c:#ifdef SPARSE_MAPPING
sys/kern/link_elf.c:#ifdef SPARSE_MAPPING
sys/kern/link_elf.c:#ifdef SPARSE_MAPPING
sys/kern/link_elf.c:#ifdef SPARSE_MAPPING
sys/kern/link_elf.c:#ifdef SPARSE_MAPPING
sys/kern/link_elf.c:#ifdef SPARSE_MAPPING
sys/kern/link_elf.c:#ifdef SPARSE_MAPPING

I proposed to remove the old/dead codes. Patch attached. Tested on amd64.
