Replace typeof() with __auto_type in the swap() macro in uffd-stress.c. __auto_type was introduced in GCC 4.9 and reduces the compile time for all compilers. No functional changes intended.

Hi,
Just a gentle follow-up on this cleanup patch. From what I could find, this is the only use of typeof() left in the mm selftests, so this should be the only instance needing this change.
Thanks for considering!
