When using Elf_Rela every tool should use the addend in the
relocation.
We have --apply-dynamic-relocs to work around bugs in tools that don't
do that.
The default value of --apply-dynamic-relocs should be false to make
sure these bugs are more easily found in the future.

When resolving dynamic RELA relocations the addend is taken from the
relocation and not the place being relocated. Accordingly lld does not
write the addend field to the place like it would for a REL relocation.
Unfortunately there is some system software, in particlar dynamic loaders
such as Bionic's linker64 that use the value of the place prior to
relocation to find the offset that they have been loaded at. Both gold
and bfd control this behavior with the --[no-]apply-dynamic-relocs option.
This change implements the option and defaults it to true for compatibility
with gold and bfd.
