Conservatively grant access to packages_list_file to everything that had
access to system_data_file:file even if the comment in the SELinux
policy suggests it was for another use.
Ran a diff on the resulting SEPolicy, the only difference of domains
being granted is those that had system_data_file:dir permissiosn which
is clearly not applicable for packages.list
diff -u0 <(sesearch --allow -t system_data_file ~/sepolicy | sed 's/system_data_file/packages_list_file/') <(sesearch --allow -t packages_list_file ~/sepolicy_new)
