Request correct rendering type for EGL config

According to [1] :
section 3.4 :
...
Creation of a client API context based on an EGLConfig will
fail unless the EGLConfig’s EGL_RENDERABLE_TYPE attribute
include the bit corresponding to that API and version.
...

section 3.7.1.6:
...
An EGL_BAD_MATCH error is generated if config does not support the
requested client API. This includes requesting creation of an OpenGL ES
1.x, 2.0, or 3.0 context when the EGL_RENDERABLE_TYPE attribute of config
does not contain EGL_OPENGL_ES_BIT, EGL_OPENGL_ES2_BIT, or EGL_-
OPENGL_ES3_BIT respectively.
...

Bootanimation uses EGL_CONTEXT_CLIENT_VERSION  2 for context creation,
so appropriate EGL_RENDERABLE_TYPE should be requested during eglChooseConfig.
