#545 but applied to rel-0.103 to prep 0.103.16.

Proposed release notes:

Distrust a small set of intermediate certificate subject public keys due to specific security concerns around their operation.

Match SPKI bytes throughout the path, including leaves and trust
anchors against a static list of distrusted keys. Keys that match are
rejected as distrusted for path building purposes.

Resolve NOSTD_TARGET through the GitHub Actions env context when
passing it to rust-toolchain. The action previously inserted the input
into shell source, which expanded the variable. Its updated argument
handling preserves the literal value, causing toolchain installation
to fail in both no-std jobs.
