    kexec-tools: add zstd to package dependencies
    
    Fixed build failure caused by missing libzstd dependency.
    
    Added CONFIG_KEXEC_ZSTD configuration option and libzstd library dependency
    declaration, following the same pattern as existing zlib and lzma support.
    
    Fixes: e75218ef4a27 ("kexec-tools: bump to 2.0.32")
