fix(bootloader_support): check the secure version only for app image
Secure version in the image header is only available for the application
image. However, for certain security workflows, bootloader verifies
itself (own image) and hence the secure version check during that must be
avoided.

Regression introduced in recent commit-id: 3305cb4d

Tested that both secure boot and flash-enc workflows work correctly
with the anti-rollback scenario.

Bootloader Support Component
============================

Overview
--------

"Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app.

Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
