fs: ensure $(TARGET_DIR_WARNING_FILE) is writable

Browse Source 
If the Buildroot tree is read-only, then $(TARGET_DIR_WARNING_FILE) is
copied read-only into target/ but we may want to remove it during the
build process.

This poses no real problem, since target/ itself is guaranteed to be
writable, but for good measure, force $(TARGET_DIR_WARNING_FILE) to be
writable itself.
