Add Debian/Armbian support to Linux mirror configuration

[Copilot]

The Linux mirror update functionality only supported Alpine Linux (/etc/apk/repositories), causing Debian/Armbian systems to fail with malformed URLs containing repeated path segments: /armbian/dists/armbian/dists///armbian/armbian/armbian/debian.

Changes

• Distribution detection: Check for both /etc/apt/sources.list and /etc/debian_version to identify Debian-based systems
• Debian/Armbian handling:
  • Extract current mirror URL from sources.list via regex /^deb\s+(https?:\/\/[^\s]+)/m
  • Replace URLs in both /etc/apt/sources.list and /etc/apt/sources.list.d/ directory
  • Execute apt-get update after mirror changes
• Security: Escape backslashes, forward slashes, and dots in URLs for sed commands to prevent injection
• Backward compatibility: Alpine Linux logic unchanged

Implementation

// Detect Debian-based systems
const hasAptSourcesList = await fs.promises.access('/etc/apt/sources.list')
  .then(() => true).catch(() => false);
const hasDebianVersion = await fs.promises.access('/etc/debian_version')
  .then(() => true).catch(() => false);
const isDebianBased = hasAptSourcesList || hasDebianVersion;

if (isDebianBased) {
  // Extract and replace mirror URL with proper escaping
  const escapedDefault = defaultDomain
    .replace(/\\/g, '\\\\')
    .replace(/\//g, '\\/')
    .replace(/\./g, '\\.');
  
  command = `sed -i 's/${escapedDefault}/${escapedTarget}/g' /etc/apt/sources.list`;
  command += ` && find /etc/apt/sources.list.d -type f \\( -name "*.list" -o -name "*.sources" \\) -exec sed -i 's/${escapedDefault}/${escapedTarget}/g' {} \\;`;
  command += ` && apt-get update`;
}

Notes

• Assumes all repositories use the same base mirror URL (replaces based on first detected mirror)
• Supports both .list and .sources file formats in sources.list.d

<issue_title>Linux 软件包镜像源地址错误</issue_title>
<issue_description>### Qinglong version

v2.20.0

Steps to reproduce

无论是使用默认地址还是阿里云还是清华源，url都会都会重复好几遍armbian

于是查看源配置文件，发现里面也存在问题，手动修改sources.list文件后正常

系统Armbian (24.11.0) aarch64，使用docker版青龙

What is expected?

正常更新软件源

What is actually happening?

无法更新软件源
