    include: store ABIVersion in Packages index
    
    With the existence of ABI versions there is no clean way to determine
    the package name without an attached ABI version. The Packages index is
    stored on device to know what packages are installed.
    
    The ABIVersion was recently removed in c921650382 "build: drop ABI
    version from metadata", while ABI versions still exists. This becomes a
    problem if a user tries to export installed packages via `ubus call
    rpcd-sys packagelist` which would return package names including the ABI
    version. Trying to find these packages in a later release with changes
    ABI version is impossible.
    
    This commits adds the `ABIVersion` field again. Knowing both the
    combined (SourceName + ABIVersion) and the `ABIVersion` it is possible
    to calculate the package `SourceName` without storing it in the
    on-device package list.
