tools headers: Sync linux/gfp_types.h with kernel sources

To pick up changes from:

  4c0a17e ("slab: prevent recursive kmalloc() in alloc_empty_sheaf()")

This would be used to handle GFP masks in the perf code and address these
tools/perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/include/linux/gfp_types.h include/linux/gfp_types.h

Please see tools/include/uapi/README.
