binutils, ld: make objdump --ctf's parameter optional

ld by default (and always, unless adjusted with a hand-rolled linker
script) emits deduplicated CTF into the .ctf section.  But viewing
it needs you to explicitly tell objdump this: it doesn't default
its argument, even though what you always end up typing is
--ctf=.ctf.

This is annoying, so make the argument optional.
