x86: Get rid of dubious one-bit signed bitfield

This very noisy sparse warning appears on almost every file in
the kernel:

  CHECK   init/main.c
  arch/x86/include/asm/thread_info.h:43:55: error: dubious one-bit
  signed bitfield arch/x86/include/asm/thread_info.h:44:46: error:
  dubious one-bit signed bitfield

Sparse is right and this patch changes sig_on_uaccess_error and
uaccess_err flags to unsigned type and thus fixes the warning.
