tests:  Migrate screenshot code from internal test to client helpers

These routines provide test cases an ability to capture screen images
for rendering verification.

This commit is a no-change refactoring, except for making the routines
non-static.  Makefile rules are also updated; most notably, this links
test clients against the cairo libraries now.

v2: Fix pointer code styling, suggested in review
