[PATCH] uml: change interface to boot_timer_handler 

Current implementation of boot_timer_handler isn't usable for s390.  So I
changed its name to do_boot_timer_handler, taking (struct sigcontext *)sc as
argument.  do_boot_timer_handler is called from new boot_timer_handler() in
arch/um/os-Linux/signal.c, which uses the same mechanisms as other signal
handler to find out sigcontext pointer.
