tools: Update include/uapi/linux/fcntl.h copy from the kernel

To get the changes in the commit c75b1d9421f8 ("fs: add fcntl()
interface for setting/getting write life time hints").

Silencing this perf build warning:

  Warning: include/uapi/linux/fcntl.h differs from kernel

We already beautify the fcntl cmd argument, so an upcoming cset will
update the 'cmd' strarray to cover these new commands.

The hints are in the 3rd arg, a pointer, so not yet supported in 'perf
trace', for that we need to copy it somehow, probably using eBPF, a new
attempt at doing that is planned.
