update.py: fix splitting on _ when getting class inheritance

The code to populate the inherits information was using a function
designed to get the recipe name from a file path, but unlike recipe
filenames, the underscore isn't treated as special in class filenames
and in fact it's quite common to use underscores there; we were ending
up with items in the inherit list such as "populate" and "rootfs". Use
the standard python os.path functions to do the splitting instead and
avoid this.
