[PATCH] externalsrc: fix duplicate entries in .git/info/exclude

[Aditya Kurdunkar <adityakurdunkar2@gmail.com>]

`readlines()` preserves trailing newlines, so the duplicate check
against the stripped link name never matched. Strip lines before
comparing to prevent repeated entries on each devtool modify run.
