render/egl: try GBM platform if device platform fails to initialize

Browse source 
Mesa could generate EGL devices that cannot be used for eglInitialize(),
e.g. in the case of a vmwgfx device w/o 3D acceleration enabled.

Continue to try GBM platform instead of bailing out when device platform
fails to initialize.

This fixes launch of wlroots-based compositors on VirtualBox VMs w/o 3D
acceleration enabled.
