    runqemu: more verbose error message about missing qemuboot.conf
    
    When invoking "runqemu" with a mistyped image or architecture name,
    the resulting error message is about the missing qemuboot.conf,
    without any indication about the root cause:
    
     $ runqemu core-image-mimimal ext4 intel-corei7-64
     runqemu - INFO - Assuming MACHINE = intel-corei7-64
     runqemu - INFO - Running MACHINE=intel-corei7-64 bitbake -e...
     runqemu - INFO - MACHINE: intel-corei7-64
     runqemu - INFO - DEPLOY_DIR_IMAGE: 
/fast/build/refkit/intel-corei7-64/tmp-glibc/deploy/images/intel-corei7-64
     Traceback (most recent call last):
       File "/work/openembedded-core/scripts/runqemu", line 1095, in <module>
         ret = main()
       File "/work/openembedded-core/scripts/runqemu", line 1082, in main
         config.read_qemuboot()
       File "/work/openembedded-core/scripts/runqemu", line 643, in read_qemuboot
         raise Exception("Failed to find <image>.qemuboot.conf!")
     Exception: Failed to find <image>.qemuboot.conf!
    
    Including the name of the actual file the scripts expects to find plus
    adding some hints what to check for might help. The error now is:
    
     $ runqemu core-image-mimimal ext4 intel-corei7-64
     ...
     Exception: Failed to find <image>.qemuboot.conf = 
.../tmp-glibc/deploy/images/intel-corei7-64/core-image-mimimal-intel-corei7-64.qemuboot.conf (wrong image 
name or BSP does not support running under qemu?).
    
    The comment about the BSP is included because that would be the real
    reason why the file might be missing.
