tst_snippets: inject the style name to image file names

For example, qtquickcontrols2-label.qml outputs:

- qtquickcontrols2-label.png (Default)
- qtquickcontrols2-material-label.png (Material)
- qtquickcontrols2-universal-label.png (Universal)

This allows us to take screenshots with different styles without
overlapping names and error-prone manual renaming.
