system-tests: Workaround for pyftpdlib bug handling IPv6 addresses.

Hack around a bug in pyftpdlib that rejects EPRT connection due to
mismatching textual representation of the IPv6 address when the
address is not in the normalized format.  This happens when the
control connection is mangled by Linux NAT.
