[yocto] [meta-raspberrypi][PATCH] linux-raspberrypi-base.bbclass: allow -rt kernels

If the PREEMPT_RT patch is applied, the kernel version becomes, say,
4.4.32-rt43 (instead of 4.4.32). This confuses the version handling code in
this class. Update how the version string is processed so that trailing rt-
strings are properly handled, in addition to handling the existing cases.
