Revert "Reland "Exposes that the dSYM bundle contains relocation information""

This reverts commit f43ecb28537f224316be099488787335149b0f4f.

Reason for revert: failing when using a secondary toolchain which
uses a different architecture than the primary toolchain (this is
because the toolchain definitions are evaluated in the primary
toolchain, thus `current_cpu` == `target_cpu`).

Original change's description:
> Reland "Exposes that the dSYM bundle contains relocation information"
>
> This is a reland of commit 6739edea3b867e783cfdef497beb73aba4060469
>
> The original CL was reverted because the path to the relocation yml
> file was incorrect in the outputs of the linker command as the file
> includes the extension of the generated binary (e.g. $foo.so.yml)
> but it was missing.
>
> This version correctly uses "{{output_extension}}" to include the
> output extension if necessary when generating the list of outputs.
