Subject: Add TRUST_LIBSCRYPT_SALT_GEN build option

Modern versions of libscrypt now generate salt correctly,
indeed using the very method currently used by lua-scrypt.[1]

This patch adds a build option that is disabled by default,
when enabled lua-scrypt will use libscrypt's salt generation code
rather than its own.
