U-boot version is stripped
For support and debugging purposes, we need to know which exact U-boot version was compiled and if it comes from us.
Actual behavior:
== U-Boot version ==
U-Boot SPL 2022.01 (Jan 27 2022 - 00:24:34 +0000)
U-Boot 2022.01 (Jan 27 2022 - 00:24:34 +0000)
Expected behavior:
U-Boot 2022.01 (Jan 27 2022 - 00:24:34 +0000), Build: jenkins-turris-os-packages-burstlab-omnia-216
The diagnostics should show us even the version behind the U-boot date. Our branch, and build version.
