移除 freebsd-pkg 的 i386 架构

[taoky]

先决条件 (Prerequisites)

• 我已确认该事宜从未在 其他 issues 中讨论过。
  I have checked that my proposal has not been discussed in other issues.

• 我已仔细阅读 请求新镜像前必读。
  I have CAREFULLY read the mirroring rules.

修改或删除的原因 (Reasons of the modification or removal)

1. 所有 freebsd-pkg 的上游均访问缓慢，无法在两日内完成正常的增量同步。

2. i386 架构使用率低，且非 tier-1 支持架构：

   $ cat access.log-20250128 | grep freebsd-pkg | grep amd64 | grep -v Mozilla | wc
      7837   94088 1206775
   $ cat access.log-20250128 | grep freebsd-pkg | grep i386 | grep -v Mozilla | wc
        16     192    2172
   $ cat access.log-20250128 | grep freebsd-pkg | grep aarch64 | grep -v Mozilla | wc
         0       0       0

配置方法 (Configuration method)

修改后的镜像大小 (Mirror size after modification)

-500 GB
