x86/callthunks: Use EXPORT_PER_CPU_SYMBOL_GPL() for per CPU variables

Sparse complains rightfully about the usage of EXPORT_SYMBOL_GPL() for per
CPU variables:

  callthunks.c:346:20: sparse: warning: incorrect type in initializer (different address spaces)
  callthunks.c:346:20: sparse:    expected void const [noderef] __percpu *__vpp_verify
  callthunks.c:346:20: sparse:    got unsigned long long *

Use EXPORT_PER_CPU_SYMBOL_GPL() instead.
