Bitbake adds default file patterns to FILES:${PN}, like ${bindir}/*,
${libdir}/lib*.so, and ${libdir}/${BPN}. Now that we have all components
split into OpenHarmony packages, we remove these patterns to make sure
we don't accidentally include any file in FILES:${PN} that should belong
to an OpenHarmony package.
