[X2Go-Dev] Bug#1508: non Latin 1 passwords are rejected

Package: x2goclient Version: 4.1.2.2

Passwords with accents are rejected by x2goclient while working fine directly with ssh.

Client OS Ubuntu 20.04.1 LTS with libssh 0.9.3-2ubuntu2.1 Server OS Ubuntu 16.04.6 LTS

According to the documentation of ssh_userauth_password(), passwords should be passed as UTF-8. But sshmasterconnection.cpp passes auth_password.toLatin1(). I think just changing to auth_password.toUtf8() should suffice.

Same thing goes for ssh_userauth_kbdint_setanswer() and maybe other calls.
