[Pkg-rust-maintainers] Bug#1103026: rust-bitfields: autopkgtest failure

Hi all,

Please find attached a patch to fix rust-bitfield's autopkgtest. What's
happening here is tests expect the stderr of compile failures to be produced by
version nightly-2024-12-15 of the rust toolchain, but our current toolchain
outputs slightly different text, so the expected stderr needs to be adapted.
I've also filed MR [1] so we can directly upload to unstable after the freeze
ends.

Cheers!

Description: Adapt tests' stderr to Debian's rust toolchain
 Tests in this package expect the stderr of compile failures to be produced by
 version nightly-2024-12-15 of the rust toolchain (as per the source
 repository's rust-toolchain.toml). Our current toolchain outputs slightly
 different text, so the expected stderr needs to be adapted. This patch
 introduces no functional differences. It must not be forwarded since upstream
 made an intentional choice of toolchain which is not compatible with this
 patch.
