kernels: linux-libre: configuration: make sure that no user input is required

Sometimes the defconfig and the source code are out of sync, this
can result in issues like this one:
  |  ==> Starting build()...
  |  scripts/kconfig/conf  --syncconfig Kconfig
  |  *
  |  * Restart config...
  |  *
  |  *
  |  * General architecture-dependent options
  |  *
  |  OProfile system profiling (OPROFILE) [M/n/y/?] m
  |    OProfile multiplexing support (EXPERIMENTAL) (OPROFILE_EVENT_MULTIPLEX) [N/y/?] n
  |  Kprobes (KPROBES) [Y/n/?] y
  |  Optimize very unlikely/likely branches (JUMP_LABEL) [Y/n/?] y
  |    Static key selftest (STATIC_KEYS_SELFTEST) [N/y/?] n
  |  Stack Protector buffer overflow detection (STACKPROTECTOR) [Y/n/?] (NEW)

This makes sure that in such case, the default choice is used instead of
asking the user about it.
