spec: Take the ownership over '/usr/libexec/ipa/custodia'
    
    Ideally, an every file on system has to have an owner.
    
    '/usr/libexec/ipa/custodia' directory was added recently, but:
    
    ```
    [root@dc ~]# LANG=C rpm -qf /usr/libexec/ipa/custodia/ipa-custodia-dmldap
    freeipa-server-4.8.4-2.fc31.x86_64
    [root@dc ~]# LANG=C rpm -qf /usr/libexec/ipa/custodia
    file /usr/libexec/ipa/custodia is not owned by any package
    ```
    
    ALTLinux build system warns about files or directories which were
    'created' during a package installation but haven't an owner. So,
    after the resyncing spec file to upstream's one my build fails.
