Manifest path logic gets wrong localWorkspacePath, breaks require

[alexeagle]

When we resolve from a RUNFILES_MANIFEST_FILE (generally Windows only), then we load the runfiles manifest and do some path logic on it to power later resolutions.

A manifest typically looks like

bazel_tools/tools/bash/runfiles/runfiles.bash C:/users/alexeagle/_bazel_alexeagle/7yoikqcr/external/bazel_tools/tools/bash/runfiles/runfiles.bash
build_bazel_rules_nodejs/packages/terser/test/inline_sourcemap/out.min.js C:/users/alexeagle/_bazel_alexeagle/7yoikqcr/execroot/build_bazel_rules_nodejs/bazel-out/x64_windows-fastbuild/bin/packages/terser/test/inline_sourcemap/out.min.js
build_bazel_rules_nodejs/packages/terser/test/inline_sourcemap/out.min.js.map C:/users/alexeagle/_bazel_alexeagle/7yoikqcr/execroot/build_bazel_rules_nodejs/bazel-out/x64_windows-fastbuild/bin/packages/terser/test/inline_sourcemap/out.min.js.map
build_bazel_rules_nodejs/packages/terser/test/inline_sourcemap/spec.js C:/users/alexeagle/documents/github/rules_nodejs/packages/terser/test/inline_sourcemap/spec.js

We iterate through these entries and skip to the last one, thanks to this logic:
https://github.com/bazelbuild/rules_nodejs/blob/df37fca0113f9e7e7536185cb907e2e6ca9e33f2/internal/node/node_loader.js#L126-L129
so we print

[test_loader.js] using localWorkspacePath C:/users/alexeagle/documents/github/rules_nodejs/

and things work.

However, if the manifest has a new entry that appears higher, and is under the output_base but not under the bin_dir (like the linker.js I was adding in #1079) then the manifest starts like this

bazel_tools/tools/bash/runfiles/runfiles.bash C:/users/alexeagle/_bazel_alexeagle/7yoikqcr/external/bazel_tools/tools/bash/runfiles/runfiles.bash
build_bazel_rules_nodejs/internal/node/node_loader.js C:/users/alexeagle/_bazel_alexeagle/7yoikqcr/external/build_bazel_rules_nodejs/internal/node/node_loader.js

The second entry isn't matched by the short-circuit logic, so it gets used. then we print
[test_loader.js] using localWorkspacePath C:/users/alexeagle/_bazel_alexeagle/7yoikqcr/external/build_bazel_rules_nodejs/
and later module resolutions fail.
