selftests: kvm: remove meaningless assignments in Makefiles

$(shell ...) expands to the output of the command. It expands to the empty string when the command does not print anything to stdout. Hence, $(shell mkdir ...) is sufficient and does not need any variable assignment in front of it. Commit c2bd08b ("treewide: remove meaningless assignments in Makefiles", 2024-02-23) did this to all of tools/ but ignored in-flight changes to tools/testing/selftests/kvm/Makefile, so reapply the change.
