rustdoc: Doctest merging: Remove superfluous library search path logic

[fmease]

Implements: #137899 (comment). Abridged:

I'm wondering, is [copying --externs from bundle crates to runner crates as -Ls] actually necessary? Did you have a concrete case where this was needed?

Locally I've experimented with the consequences of removing it, couldn't find any problems and all tests pass without it, too. It's possible that I missed something.

Everything seems to work out just fine without this extra logic because any --externs and -Ls (most likely -Ldependency=s from Cargo) passed to rustdoc for the "overarching host crate" (the crate containing the doctest) get stuffed into the args file rustdoc-cfgs which we use for compiling both the bundle and the runner.

With COMPILETEST_FORCE_STAGE0=1 ./x t --stage 0 tests/run-make/doctests-merge-with-deps you should be able to verify that the test also passes on master.

r? notriddle or reassign and no rush

Also note for additional context: This didn't apply to doctest-only dependencies "anyway"¹ as registered via -Zunstable-options --doctest-compilation-args as noted here: #137899 (comment)

Footnotes

1. Very unlikely to occur in practice due to Cargo's dominance which doesn't support that. ↩

Maybe also explicitly add a "2015" edition, since that IIRC influences extern prelude behavior (in 2015, extern extern_prelude; is still needed even if you specify --extern to rustc IIRC).

Clearly not superfluous, I didn't run any rmake tests back in #137899 (comment). Without these extra -Ls we silently fall back to unmerged doctest execution in tests/run-make/doctests-keep-binaries-2024.

I'm not sure my new test still pulls its weight with that said despite passing on master, too.

I'll close this PR and experiment a bit locally with all of this.
