    package_ipk.bbclass: Replace empty lines in DESCRIPTION with '.'
    
    opkg uses empty lines as separator for next package and if an ipk file was
    packaged with empty lines in DESCRIPTION opkg won't be able to handle such ipk
    file, this happens at execution time.
    
    This commit will replace empty lines in DESCRIPTION with a '.' when generating
    an ipk package to avoid this issue.
