vfio: selftests: Drop <uapi/linux/types.h> includes

Drop the <uapi/linux/types.h> includes now that <linux/types.h>
(tools/include/linux/types.h) has a definition for __aligned_le64, which
is needed by <linux/iommufd.h>.

Including <uapi/linux/types.h> is harmless but causes benign typedef
redefinitions. This is not a problem for VFIO selftests but becomes an
issue when the VFIO selftests library is built into KVM selftests, since
they are built with -std=gnu99 which does not allow typedef redifitions.

No functional change intended.
