Subject: [PATCH] main: Don't add an extra separator when the title version is
 absent

Some titles, such as homebrew, do not have any version string. Because
yuzu hard codes the title bar string assuming a version string is
preset, booting homebrew causes yuzu to add an extra separator with no
content between.

This uses a lambda expression to prevent that from happening.
