Revert "Uprev libmtp to 1.1.12"

util/mtp-probe.c

 /**
  * \file mtp-probe.c
  * Program to probe newly connected device interfaces from
  * userspace to determine if they are MTP devices, used for
  * udev rules.
  *
  * Invoke the program from udev to check it for MTP signatures,
  * e.g.
  * ATTR{bDeviceClass}=="ff",
  * PROGRAM="<path>/mtp-probe /sys$env{DEVPATH} $attr{busnum} $attr{devnum}",
