kgdbts: fix return value of __setup handler

__setup() handlers should return 1 to indicate that the boot option
has been handled. A return of 0 causes the boot option/value to be
listed as an Unknown kernel parameter and added to init's (limited)
environment strings. So return 1 from kgdbts_option_setup().

Unknown kernel command line parameters "BOOT_IMAGE=/boot/bzImage-517rc7
  kgdboc=kbd kgdbts=", will be passed to user space.

 Run /sbin/init as init process
   with arguments:
     /sbin/init
   with environment:
     HOME=/
     TERM=linux
     BOOT_IMAGE=/boot/bzImage-517rc7
     kgdboc=kbd
     kgdbts=
