linux-yocto: custom repo fixes

Richard/Saul,

I worked through some custom repository issues over the past day, and the outcome is two small patches to fix some corner cases. I've tested these with the standard linux-yocto recipes, with my base linux-yocto-custom, eternalsrc and the repositories that were showing the error.

(patches are stacked on my yocto base, but that history has no impact).

Cheers,

Bruce

1.7.5.4

The commit a9f11849 [linux-yocto: explicitly export KMETA to scripts] allows the meta branch name to be changed by exporting it to all phases of the build.

But if a custom kernel without a meta branch is built, we end up passing an empty string to the creation scripts, which breaks the build since input is expected.

Inhibiting the export of KMETA to the creation scripts when empty fixes the problem.

1.7.5.4

To support custom repositories that set a SRCREV and that only have a single master branch, do_validate_branches needs a special case for 'master'. We can't delete and recreate the branch, since you cannot delete the current branch, instead we must reset the branch to the proper SRCREV.
