build system: fix parallel building issue
The files generated by the include/config/MARKER target are in the dependency list for applets/applet_tables. If applets/applet_tables is created first during applets_dir then it will be created again later as part of $(busybox-dirs). As a result include/applet_tables.h is created again. This time while other build commands may need it. Let applets_dir depend on include/config/MARKER to avoid this particular race condition and create the header files atomically to ensure that the compiler never sees incomplete files.
