pkg/config: fix comments stripping

The comment-stripping regex doesn't work for multi-line comments,
because the regex looks for a substring that both starts _and_ ends with
a newline character. Since a single newline cannot be used into multiple
matches, only the first comment line is found and later lines are not
removed resulting in a parsing error.

Fix it by looking for substrings _until_ a newline.
