[PATCH] installer: Auto-select image when only one is available

[Shivaschandra KL]

Currently, the image selection dialog is always shown,
even when only a single image is available. Even when the single
image is availble, first window asks to select image and second window
asks to start installation of same image.No selection required if there
is only one image.

This change modifies ui_select_image_menu() to automatically select the
image when only one installable entry is found, while preserving the
dialog for multiple images.

Benefits:
- Improved user experience for single-image installations
- Maintains existing behavior for multi-image scenarios
