perf bench mem: Ignore export.h related changes to mem{cpy,set}.S

Ignore export.h and EXPORT_SYMBOL in:

  784d5699eddc ("x86: move exports to actual definitions")

We're not dragging this stuff, not useful in tools/

This silences the following warnings while building perf:

  Warning: tools/arch/x86/lib/memcpy_64.S differs from kernel
  Warning: tools/arch/x86/lib/memset_64.S differs from kernel
