tools: Remove length check on device UDID arguments to support newer devices
The 40 characters length check on the device UDID made newer devices unusable
with the libimobiledevice tools and was actually redundant since an invalid
UDID will always fail to resolve. This commit removes the length check
alltogether (but makes sure it is not an empty string "").
