tools headers uapi: Sync linux/usbdevice_fs.h with the kernel sources

To pick up the changes from:

  4ed3350539aa ("USB: usbfs: Add a capability flag for runtime suspend")
  7794f486ed0b ("usbfs: Add ioctls for runtime power management")

This triggers these changes in the kernel sources, automagically
supporting these new ioctls in the 'perf trace' beautifiers.

Soon this will be used in things like filter expressions for tracepoints
in 'perf record', 'perf trace', 'perf top', i.e. filter expressions will
do a lookup to turn things like USBDEVFS_WAIT_FOR_RESUME into _IO('U',
35) before associating the tracepoint expression to tracepoint perf
event.
