lib: gem_set_caching() use drmIoctl() rather than ioctl()

Browse Source 
gem_set_caching() tries to be clever and detect when the ioctl isn't
supported (thereby skipping the test). However, it forget that we may be
acting on active objects and be subject to the usual EAGAIN/EINTR
errors. We can use the drmIoctl() to wrap the raw ioctl() in order to
get the automatic restart on the interrupted syscall.
