tools headers: Sync UAPI linux/fcntl.h with kernel sources

To pick up changes from:

  fe93446 ("vfs: use UAPI types for new struct delegation definition")
  4be9e04 ("vfs: add needed headers for new struct delegation definition")
  1602bad ("vfs: expose delegation support to userland")

This should be used to beautify fcntl syscall arguments and it addresses
these tools/perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/perf/trace/beauty/include/uapi/linux/fcntl.h include/uapi/linux/fcntl.h

Please see tools/include/uapi/README.
