oeqa/selftest/rust: add missing zlib and zstd dependencies

LLVM requires zlib and zstd support for compression routines
used by rustc_codegen_llvm and related components.

Recipe-level RUSTFLAGS are not propagated in qemu image, causing bootstrap
test linkage failures. When these libraries are absent in the selftest
execution environment, bootstrap test binaries fail to link and cause
following failure:

  error: linking with `target-rust-ccld` failed: exit status: 1
  = note: undefined reference to `compress2'
  = note: undefined reference to `uncompress'
  = note: undefined reference to `ZSTD_decompress'
  = note: undefined reference to `ZSTD_isError'
  = note: undefined reference to `ZSTD_compress2'
  = note: undefined reference to `crc32'

Explicitly pass `-lz` and `-lzstd` in the image and ensure the corresponding
runtime libraries are present in the image.
It was initially reported on qemuppc and later seen across all tested
architectures (arm32/64, riscv64, x86_32/64).
