runqemu bugfix [v2]

Hello,

This is a fix for Yocto bug #3112, where there are certain edge cases where the bitbake command is avalable to fails to run. Previously we mistakenly treated that as the same case as if bitbake didn't exist in the user's $PATH, and this fix causes us to show the user the output of bitbake so they can view the error message.

v2 includes rework based on feedback from Mark Hatle (thanks!).

Scott

In certain edge cases, bitbake may fail to run and cause setup_tmpdir() within runqemu to fail, and not give the user a helpful error message. Catch this case and show the user the output of bitbake -e.

This fixes [YOCTO #3112]
