The selftests build four kernel modules which use copy-pasted Makefile targets. This is a bit messy, and doesn't scale so well when we add more modules, so let's consolidate these rules into a single rule generated for each module name, and move the module sources into a single directory. To avoid parallel builds of the different modules stepping on each other's toes during the 'modpost' phase of the Kbuild 'make modules', the module files should really be a grouped target. However, make only added explicit support for grouped targets in version 4.3, which is newer than the minimum version supported by the kernel. However, make implicitly treats pattern matching rules with multiple targets as a grouped target, so we can work around this by turning the rule into a pattern matching target. We do this by replacing '.ko' with '%ko' in the targets with subst().
