    package.bbclass: Restore functionality to detect RPM dependencies
    
    During the transition to dnf and rpm4, the functionality to
    automatically make RPM determine dependencies was lost.
    
    Before the transition, an OE specific tool called rpmdeps-oecore had
    been added to the rpm suit. It was based on the rpmdeps tool that is
    part of rpm. For each file specified on its command line, it would
    output the provides and requires that RPM could determine.
    
    During the transition to rpm4, rpmdeps-oecore was replaced with the
    standard rpmdeps. However, what no one noticed was that unless rpmdeps
    is given options, e.g., -P or -R, to tell it what it should output, it
    will not output anything. Thus, it would do all the work to determine
    the requirements, but would keep silent about it. And since no output
    from rpmdeps is expected unless there are requirements, there were no
    warnings indicating that everything was not working as expected.
    
    Porting the old rpmdeps-oecore to work with rpm4 is not really
    possible since it relied on being able to access internals of RPM that
    are no longer available. However, it turned out that rpmdeps had a
    debug option, --rpmfcdebug, that would output exactly the information
    that we need, albeit in a different format and to stderr. To make this
    usable, rpmdeps has now received a new option, --alldeps, which sends
    the information we need to stdout.
