util/lint: Apply `final newlines` check to scripts

The `lint-extended-015-final-newlines` script skips over executable
files and thus leaves script files unchecked.

Use `file` to find scripts and include them in the `final newlines`
checks. Whitelisting is used including bash, perl, python and sh
scripts.
