alphaplan_fwr: Create u-boot package from imx-boot.tar.gz if found

The main install file for u-boot changed to imx-boot.tar.gz, so this should be added to alphaplan. Leaving the imx-boot implementation as fallback.

CI: Modifications to enable reproducible builds

Added default source revision file name to common.py. Modified the integration_into_manifest function to set the corresponding subproject hash in the SRCREV.conf file if the repository is not found in the default.xml file. The merge_into_manifest function now works even if the names of the master branches in the manifest and in the project repository are different.
