Add 60s timeout for acquiring the APT lock

[mpurg]

Description:

• Add 60s lock timeout to apt-get commands

Rationale:

• This largely mitigates the issue of packages failing to install due to other apt processes (unattended-upgrades) running in the background at the same time.
• By default, apt-get fails immediately if another apt process holds the lock, and there's no good way to acquire the lock from a bash script.

Hi @mpurg. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
