crypto: delete built-in DES implementation
The built-in DES implementation is used for the VNC server password
authentication scheme. When building system emulators it is reasonable
to expect that an external crypto library is being used. It is thus
not worth keeping a home grown DES implementation in tree.

So qemu with only vnc without gnutls fails in that way:
error: internal error: qemu unexpectedly closed the monitor: 2022-02-01T09:30:00.449415Z qemu-system-x86_64: -vnc 127.0.0.1:34,password=on,audiodev=audio1: Cipher backend does not support DES algorithm


Works for me by just enable USE gnutls

FTR I'm using 6.2.0
