lang/rust: Update to 1.57.0

- Unbreak build with LibreSSL 3.4.x [0]
- Disable backtrace's libunwind backend on armv* since it or
  libunwind in base seem to be buggy and cause rustc to crash when
  building some consumers [1]
- Follow rust-nightly in d5f09dc31fcfdb77b69c86b9093bf67ec67653d9
  and reenable hardlinks in the build

+When the compiler has "clang" in its name the cc crate will pass
+an LLVM target triple to it.  Rust uses a triple that lacks the OS
+version and LLVM will default to FreeBSD 9 behavior, i.e., it will
+default to libstdc++ which is no longer available in newer releases.
+
+To avoid this issue assume we have a GNU compatible toolchain instead
+until LLVM can be updated to use libc++ by default.
