Introduced poky upstream commit:
14df6d53b6 linux-yocto: improve checkout error handling and reporting

converts all remote branches to local branches.
Our Linux repo has ~4500 remote branches:
git branch -a | grep remotes |wc -l  -> 4575

This costs our best workstations ~20 minutes to simply do that conversion
in do_kernel_checkout which is not needed (at least I do not see any
benefit after testing with this patch).

Since this conversion is required for some linux-yocto workflows we
introduce variable that allows skipping this on demand.
