kconfig: syzbot: avoid duplicated output

Config files from syzbot have

  CONFIG_CMDLINE="earlyprintk=serial (...) console=ttyS0 (...)"

Virtme already sets them to different values. Because virtme uses
console=hvc0 by default on some arch, the console=ttyS0 from syzbot will
cause the output to be duplicated:

  [    0.794784][    T0] Console: colour *CGA 80x25
  [    0.795159][    T0] printk: legacy console [ttyS0] enabled

  [    0.869386][    T0] Lock dependency validator: Copyright (c) 2006 Red Hat, Inc., Ingo Molnar
  [    0.870424][    T0] ... MAX_LOCKDEP_SUBCLASSES:  8
  [    0.870424][    T0] ... MAX_LOCKDEP_SUBCLASSES:  8

This is confusing, and takes some resources.
