build: fix possible issue with kmod package having multiple AutoLoad's

This commit contains the following changes

 - Use local shell var where appliable
 - The $(sort $$$$$$$$mods) call will have no expected effect
 - Avoid EEXIST when creating symlinks in /etc/modules-boot.d/
 - Avoid duplicate arguments for insert_modules() in postinst-pkg
