Make stripCommentHeaders less greedy, to ensure that it doesn't eat 'use strict' directive at the top of files (PR 6627 follow-up)

Browse Source 
While browsing through the latest PDF.js update on mozilla-central, see https://hg.mozilla.org/integration/fx-team/rev/aef06cd725fc, I noticed that the `'use strict';` directives were missing at the top of a number of files.
This is fallout from the changes made in `make.js` in PR 6627, since `stripCommentHeaders` previously relied on the existence of the mode-lines.

I'm assuming that we do want *all* of the code (e.g. the viewer too) to execute in strict mode, hence this patch tweaks `stripCommentHeaders` to make it less greedy.
