gnu: python-pylibscrypt: Improve speed.
* gnu/packages/python-crypto.scm (python-pylibscrypt): Use "libscrypt" implementation instead of "openssl". "hashlib.scrypt" requires Python 3.6+ and OpenSSL 1.1+. Since Python is built with OpenSSL 1.0, the library is unavailable. "pylibscrypt" defaults to a slow pure Python implementation. Instead, rely on the much faster "libscrypt".
