inspector: Avoid a crash with GL variants

Browse Source 
When configuring the inspector display, preserve
debug flags that affect which GL variant we pick.
Otherwise, we may end up with a GLX context on the
default display, and an EGL context on the inspector
one. This hopelessly confuses libepoxy, and things
don't go well when that happens.
