Use wangguofang.net proxy and Tsinghua mirror for GitHub and libaio downloads

Switches the remaining gh-proxy.com references (rockylinux9, debian13) to
wangguofang.net for consistency with alpine3.24, and points the libaio
0.3.113 download at the Tsinghua mirror instead of releases.pagure.org for
faster access from mainland China.
