bitbake: siggen: clean_basepath: remove recipe full path when virtual:xyz present

Before this fix, this example basepath (a):
virtual:native:/full/path/to/recipes-example/helloworld/helloworld_1.2.3.bb:do_compile
would get incorrectly "cleaned" into:
helloworld/helloworld_1.2.3.bb:do_compile:virtual:native:/full/path/to/recipes-example/helloworld/helloworld_1.2.3.bb

When searching backwards in `a` trying to isolate the 'virtual:xyz' to add
it to the end of the string, we need to consider `a` still has the recipe
path and taskname. So stoping the rsplit after only 1 split is not enough.
We want to reach the second ':' from the end.

This way, we obtain:
helloworld/helloworld_1.2.3.bb:do_compile:virtual:native
