manifest: mcuboot update

Synch up to upstream:
https://github.com/mcu-tools/mcuboot/commit/1eedec3e79



- fixed the build issue caused by removal of CONFIG_SYSTEM_CLOCK_DISABLE
property (within drivers: timer: implementation cleanups #37435)
- always call sys_clock_disable() in main since the empty
sys_clock_disable() callback is provided if the platform doesn't
support system clock disable capability.
- bootutil: Close flash_area after failure to read swap status information
- fixed status offset calculation in case of scratch area
- fixed include path for reboot.h header.
