libobs-opengl: Promote eglCreateImage failure to LOG_ERROR

Xcomposite window capture is currently failing on FreeBSD, in
gl_egl_create_texture_from_pixmap (for currently unknown reasons).
Increase the log level of the existing log for eglCreateImage failure
from LOG_INFO to LOG_ERROR to provide a hint for anyone who encounters
the same issue in the future.
