initramfs-module-bootldr-buster: Add initial code to workaround bogus system console issue.
* The main trouble is the bogus console=ttySA0 passed by bootldr
It appears that kernel doesn't have protection against only invalid
consoles being passed on the command line, which means that the
kernel is deaf and dumb when booted by bootldr.
