Hide non-channel WADs

These cannot be booted, so it is bad UX to show them in the UI as if
they were regular titles, and yet have different behaviour for them.

And technically, there is no reason to allow them to be used to boot
in the first place.

Another reason they should not be shown is that Dolphin fails
spectacularly with WADs that have a valid boot content index, but are
not PPC titles (e.g. IOS WADs). The only reliable way to avoid this
is to check for the title type and only show channels, just like
the Wii System Menu.
