    stx-extensions: use the host's PID for coredump

    systemd-coredump running as root on the host wants to get process
    information using the process' PID, but %p refers to "the PID namespace
    in which the process resides" (the container). systemd-coredump
    coredumps. Dmesg shows "Failed to get EXE" and the segfault (sic
    'systemd-coredum').

    This segfault of systemd-coredump is intermittent, and so on occasion a
    core file may actually be dumped for the containerized process. This
    happens when the %p does not match a process from the host's
    perspective. Dmesg shows "Failed to get COMM..." and "Failed to get
    EXE". This becomes more likely as the PIDs in container's namespace
    become larger - the host's PIDs are more sparse as the numbers increase.

    Use %P instead, "as seen in the initial PID namespace" (host).

    Convert the package to use PKG_GITREVCOUNT for release increment.
