sched.h: drop in_ubsan field when UBSAN is in trap mode
in_ubsan field of task_struct is only used in lib/ubsan.c, which in its turn is used only `ifneq ($(CONFIG_UBSAN_TRAP),y)`. Removing unnecessary field from a task_struct will help preserve the ABI between vanilla and CONFIG_UBSAN_TRAP'ed kernels. In particular, this will help enabling bounds sanitizer transparently for Android's GKI.
