fix: Restore working build configuration from 4fb4b353 (#204)

* fix: Resolve zstd-sys Zig compilation issues

- Remove specific Zig version constraint in action.yml to use default version
- Clean up duplicate environment variable settings in build-rustfs.sh
- Add CARGO_TARGET_*_LINKER environment variables for better cross-compilation support
- Optimize build configuration for consistent cross-platform compilation

Fixes compilation issues with zstd-sys when using Zig cross-compilation.
Aligns with previously working configuration that uses default Zig version.

* fix: Restore working build configuration from 4fb4b353

- Restore matrix.cross parameter to differentiate cross-compilation
- Use simple cargo zigbuild instead of complex build-rustfs.sh script
- Remove unnecessary zstd dependencies from action.yml
- Restore console asset download step
- Use correct target directory path for packaging
- Align with known working configuration from commit 4fb4b353

This reverts to the proven working build approach that successfully
performed cross-platform compilation.

* fix: Align build-rustfs.sh with working version logic

- Simplify build logic to match working version 4fb4b353
- Use exact same build commands as the working build.yml:
  * cargo build for native compilation
  * cargo zigbuild for Linux ARM64 cross-compilation
  * cross build for Windows ARM64 cross-compilation
- Remove complex environment variable setup that caused conflicts
- Add touch rustfs/build.rs to match working version
- Use -p rustfs --bins flag consistent with working version

This ensures build-rustfs.sh (if used) follows the proven working approach.
