gltrace: Do not start gltrace from early_egl_init.

The debugging and tracing levels are initialized both during
early_egl_init and egl_display_t::initialize(). For apps this has
no effect since early_egl_init is called in the context of zygote.
This CL removes the unnecessary call from early_egl_init.
