    oeqa/buildperf: Add 'bitbake -m' on sync function to ensure bitbake is unloaded
    
    Add 'bitbake -m' to the sync method and ensure all process related to
    bitbake are correctly unloaded before doing the different measurements.
    Also add a call to sync funtion on Test4 before final measurment of
    eSDK deploy dir disk usage.
