Use RW_SPINLOCK_USE_X86_INTRINSIC_ in RWSpinLockTest

Summary:
- This macro is computed based on whether or not we support x86
intrinsics in RWSpinLock.h; re-use it rather than re-computing
this (and getting it wrong).

Test Plan:
- fbconfig -r folly && fbmake runtests
- ./configure && make check on Ubuntu/FC/Mac
