[缺陷描述]：
安装bind软件包后，启动named.service失败，报/usr/sbin/named-checkconf: No such file or directory，导致软件兼容性测试用例失败

报错日志如下：
# systemctl status named.service
× named.service - Berkeley Internet Name Domain (DNS)
     Loaded: loaded (/usr/lib/systemd/system/named.service; disabled; preset: disabled)

Jun 07 10:57:39 iZbp1f0r7cq40w7pws3kfpZ systemd[1]: Failed to start named.service - Berkeley Internet Name Domain (DNS).

经分析：
/usr/lib/systemd/system/named.service配置了/usr/sbin/named-checkconf，但是bind软件包未提供，而是提供了/usr/bin/named-checkconf

# rpm -qf /usr/lib/systemd/system/named.service
bind-9.18.15-1.an23.aarch64

# rpm -ql bind-9.18.15-1.an23.aarch64 |grep checkconf
/usr/bin/named-checkconf
/usr/share/man/man1/named-checkconf.1.zst

[复现步骤]：
1、安装bind软件包
    yum install -y bind
2、启动named.service服务
   systemctl start bind

[预期结果]：
named.service服务启动成功

[实际结果]：
named.service服务启动失败
