tools headers UAPI: Sync usbdevice_fs.h with the kernels to get new ioctl

To get the changes in:

6d101f24f1dd ("USB: add usbfs ioctl to retrieve the connection parameters")

And address this perf build warning:

Warning: Kernel ABI header at 'tools/include/uapi/linux/usbdevice_fs.h' differs from latest version at 'include/uapi/linux/usbdevice_fs.h'
diff -u tools/include/uapi/linux/usbdevice_fs.h include/uapi/linux/usbdevice_fs.h

Which ends up autogenerating a ioctl_cmd->string table used by 'perf
trace':

$ tools/perf/trace/beauty/usbdevfs_ioctl.sh > before
$ cp include/uapi/linux/usbdevice_fs.h tools/include/uapi/linux/usbdevice_fs.h
$ tools/perf/trace/beauty/usbdevfs_ioctl.sh > after

[31] = "GET_SPEED",

Now 'perf trace' ioctl beautifier will translate this new ioctl to a
string and at some point will allow filtering the 'ioctl' syscall with
something like this in a system wide strace-like sessin:

# perf trace -e ioctl/cmd=USBDEVFS_CONNINFO_EX/
