chromium: Add mime-xdg to get rid of build warning

When building chromium without including mime-xdg, bitbake throws the
following warning:

WARNING: chromium-x11-86.0.4240.111-r0 do_package_qa:
QA Issue: package contains desktop file with key 'MimeType' but does not inhert mime

In order to deal with this error, have the chromium recipe inherit
the mime-xdg recipe.
