Text files starting with PACKAGE* get the mime type application/x-pak instead of text/plain

SUMMARY

Any plaintext file that starts with PACKAGE* and doesn't have a filename ending associated with a mime type, gets the mime type application/x-pak. This happens for example for dkms.conf file that don't have licensing information preceding and therefore start with PACKAGE_NAME=<some_name>

STEPS TO REPRODUCE

echo "PACKAGEloremipsum" > foo

OBSERVED RESULT

foo has the mime type application/x-pak

EXPECTED RESULT

foo has the mime type text/plain
