lib: Always unbind the fbcon around igt
The fbcon imposes unpredictable latencies on tests - each drmIoctl has
been observed to trigger two 650us calls to console_unlock() as it
flushes printk buffer for the DRM_DEBUG around the ioctl. This makes
tests such as gem_wait fail as they expect the ioctl to be spent on the
operation under test not clogged up by the console.
