Fix shift-overflow warning

Wrap toMB constant in UINT64_C to avoid the warning:

    src/cl_device_id.c:743:49: warning: result of
     ‘1152921504606846975l << 20’
     requires 81 bits to represent, but ‘long int’ only has 64 bits
     [-Wshift-overflow=]
        #define toMB(size) (size)&((0xfffffffffffffff)<<20)
