[yocto] [ptest-runner 1/8] Corrected return code interpreter

[Joshua Lock]

Can you add a commit message detailing what changed and why? Most of the 
commit messages in this series don't help me understand what changed and 
why: https://chris.beams.io/posts/git-commit/

This is especially important as the original author of the code has 
moved on from the project.

Why 127? That's "command not found" in bash and EKEYEXPIRED in my errno.h

Could we just include errno and use a named error code?
