treewide: drop shebang from non-executable target files

This drops the shebang from all target files for /lib and
/etc/uci-defaults folders, as these are sourced and the shebang
is useless.

While at it, fix the executable flag on a few of these files.

This does not touch ar71xx, as this target is just used for
backporting now and applying cosmetic changes would just complicate
things.
