test: Fix handling of dots in CAIRO_TEST_TARGET

Before this, the following happened:

  $ CAIRO_TEST_TARGET=image,xcb-render-0.0 make test
  Cannot find target 'image'.
  Known targets: image, [...]

The reason for this is that _cairo_boilerplate_target_matches_name() doesn't get
a null-terminated string, but instead has a pointer to the end of the string.
However, strpbrk() expects a null-terminated argument and thus could return a
result which points past the end of the input.

This commit fixes exactly this.
