coredump/elf: Pass coredump_params into fill_note_info

commit 9ec7d3230717b4fe9b6c7afeb4811909c23fa1d7 upstream.

Instead of individually passing cprm->siginfo and cprm->regs
into fill_note_info pass all of struct coredump_params.

This is preparation to allow fill_files_note to use the existing
vma snapshot.
