rpi-update: Only update 32/64 bit kernel and modules if currently present

Browse Source 
We've seen reports of 64-bit distributions that rely on the absence of a 32-bit kernel
to get firmware to switch to 64-bit mode (rather that explicitly using arm_64bit=1),
and that assumption is broken when adding 32-bit kernels to the boot directory
