Use cloud-local APT sources

[int128]

This will improve the time of apt-get update and install on AWS EC2.

How it works

This adds an entrypoint script to modify /etc/apt/sources.list when a runner is on AWS EC2. It depends on the metadata endpoint of IMDSv2.

Actual content of /etc/apt/sources.list

Ubuntu 22.04 EC2 x86:

$ cat /etc/apt/sources.list | egrep -v '^#|^$'
deb http://ap-northeast-1.ec2.archive.ubuntu.com/ubuntu/ jammy main restricted
