xrandr: calloc XRRModeInfo's passed to libXrandr.

The "--newmode" commandline option initializes an XRRModeInfo and passes
it into XRRCreateMode().  calloc(3) it to avoid uninitialized fields.
For consistency, calloc(3) all the places where umode_t's (the wrapper
structure for XRRModeInfo) are allocated.
