fix: add musl cross-compilation tools for ARM targets

- Install musl-tools for musl targets on ARM runners
- Set CC and linker environment variables for aarch64-musl target
- Set CC environment variable for armv7-musl target
- Fix shellcheck issues with string comparisons
- This fixes zstd-sys build errors for musl targets
