tools headers: Sync uapi/linux/fs.h with the kernel source
To pick up the changes in this cset:
76fdb7eb4e1c9108 uapi: export PROCFS_ROOT_INO
ca115d7e754691c0 tree-wide: s/struct fileattr/struct file_kattr/g
be7efb2d20d67f33 fs: introduce file_getattr and file_setattr syscalls
9eb22f7fedfc9eb1 fs: add ioctl to query metadata and protection info capabilities
This addresses these perf build warnings:
Warning: Kernel ABI header differences:
diff -u tools/perf/trace/beauty/include/uapi/linux/fs.h include/uapi/linux/fs.h
Please see tools/include/uapi/README for further details.
