tools include UAPI: Update copy of files related to new syscalls
Copy the headers changed by these csets:
cf3cba4a429b ("vfs: syscall: Add fspick() to select a superblock for reconfiguration")
93766fbd2696 ("vfs: syscall: Add fsmount() to create a mount for a superblock")
ecdab150fddb ("vfs: syscall: Add fsconfig() for configuring and managing a context")
24dcb3d90a1f ("vfs: syscall: Add fsopen() to prepare for superblock creation")
2db154b3ea8e ("vfs: syscall: Add move_mount(2) to move mounts around")
a07b20004793 ("vfs: syscall: Add open_tree(2) to reference or clone a mount")
We need to create tables for all the flags argument in the new syscalls,
in followup patches.
This silences these perf build warnings:
Warning: Kernel ABI header at 'tools/include/uapi/linux/mount.h' differs from latest version at 'include/uapi/linux/mount.h'

Warning: Kernel ABI header at 'tools/perf/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl'
