tools/include: Sync uapi/linux/fs.h with the kernel sources 



To pick up the changes from:

  41bcbe59 ("fs: FS_IOC_GETUUID")
  ae8c5117 ("fs: add FS_IOC_GETFSSYSFSPATH")
  73fa7547 ("vfs: add RWF_NOAPPEND flag for pwritev2")

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

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