x86/debug: Fix the printk() debug output of signal_fault(), do_trap() and do_general_protection()

Since commit:

  4bcc595ccd80 "printk: reinstate KERN_CONT for printing"

... the debug output of signal_fault(), do_trap() and do_general_protection()
looks garbled, e.g.:

 traps: conftest[9335] trap invalid opcode ip:400428 sp:7ffeaba1b0d8 error:0
  in conftest[400000+1000]

(note the unintended line break.)

Fix the bug by adding KERN_CONTs.
