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".
