Transformer GL: Remove UnsupportedEglVersionException().

UnsupportedEglVersionException() is only used once, and seems a bit too
specific for Transformer. Also, it's possible for eglCreateContext to fail for
other reasons besides lack of support, so it wasn't always accurate when
thrown.

It is possible for devices not to support EGL version 2.0 though, per
https://source.android.com/devices/graphics/implement-opengl-es, which doesn't
specify the EGL version that must be supported.
