elf.5: add readelf cross-reference

objdump is sometimes used in cases where readelf is more appropriate,
but the obsolete GNU objdump we have in the base system will be removed
in the future.

.Xr readelf from elf.5 to improve the odds the more appropriate tool
will be found.

ldd: reference readelf instead of objdump in warning message

We have an obsolete GNU objdump 2.17.50 in the base system, which will
be removed in the future. Suggest readelf(1) for examining ELF files
instead; for most use cases it is the preferred tool anyhow.
