package/linux-tools: change method for including linux-tool sub-makefiles
Make inclusion ordering of all linux-tool-*.mk sub-makefiles explicit instead of relying on alphabetical sort order. This is done by renaming the Linux tools sub-makefiles to the format linux-tool-*.mk.in. This causes the top-level Makefile to ignore the Linux tools sub-makefiles. Until now, the main Makefile included all linux-tool-*.mk files, as well as linux-tools.mk, and it relied on alphabetical sorting to include them in the proper order (linux-tool-*.mk before linux-tools.mk).
