enable CL_DEVICE_HOST_UNIFIED_MEMORY when userptr is supported

userptr is firstly checked at compile time with libdrm version, but
it does not ensure the system has such capability (for exmaple, with
old linux kernel), so also take a check at run time for the device info.

V2: add runtime check to see if userptr is really supported
