util: fix parseEnv handling of invalid lines

[AugustinMauroy]

This PR fixes an issue with util.parseEnv() where invalid lines in the input were being incorrectly concatenated into key names instead of being skipped. The fix ensures that lines without an equals sign are properly skipped during parsing

Fixes: #56775

Nice work!

Even though this test pass, I strongly recommend adding as much as comment possible while simplifying your code. Our parser is already complex (due to not using a regex) and it would help a lot if we know why such decision is taken in the parser.

This should work make test-only (for c and js)

if it is a specific js test ./node test-name.js
