Subject: [PATCH] scripts: checkpatch: remove preceding dot-slash from path name

In case checkpatch is called with a path name that starts with ./ for
the current directory not all issues are being reported since internal
path checks don't succeed. This patch removes the leading './' from
$filename. This is needed to have checkpatch report all issues found
during execution.
