PATCH: PR binutils/18209: objdump -h is not very helpful printing decompressed section names

Change compressed input debug section name for objdump is very
confusing. But we need to change it for linker so that linker will
consider th section as a debug section. This patch delays section
rename to elf_fake_sections for objcopy and avoids it for objdump.
OK for master?
Thanks.
H.J.
