    build: use STAGING_DIR for special APK package versions
    
    Removing tmp/ after having built base-files or toolchain currently
    breaks rootfs generation:
    
    $ rm -rf tmp
    $ make V=w
    ...
     make[2] package/install
    cat: .../openwrt/tmp/base-files.version: No such file or directory
    cat: .../openwrt/openwrt/tmp/libc.version: No such file or directory
    ERROR: 'base-files=' is not a valid world dependency, format is name(@tag)([<>~=]version)
    make[2]: *** [package/Makefile:100: package/install] Error 99
    
    The only way to recover from here is to clean toolchain and base-files via
    
    $ make package/{base-files,toolchain}/clean
    
    tmp is supposed to be ephemeral, so clearing it is an expected action,
    which normally just triggers a regeneration of all files there.
    
    Fix this by moving the version files to $(STAGING_DIR).
