tst_snippets: take screenshots only when requested

The component loading code has been adjusted so that it can load
snippets that use either a Window root element too.

This speeds up the test a lot in the CI, and allows us to flatten
the snippet-structure. Set SCREENSHOTS=1 environment variable to
take screenshots.
