s390: Always enable EXPOLINE_EXTERN if supported

Browse source

Since commit ba05b39d54 ("s390/expoline: Make modules use kernel
expolines"), there is no longer any reason not to use
CONFIG_EXPOLINE_EXTERN when supported by the compiler.

On the positive side:
- there is only a single set of expolines generated and used by both the
  kernel code and modules,
- it eliminates expolines "comdat" sections, which can confuse tools
  like kpatch.

Always enable EXPOLINE_EXTERN if supported by the compiler.
