RFR: 8260460: GitHub actions still fail on Linux x86_32 with "Could not configure libc6:i386"

[Aleksey Shipilev]

See for example:
 https://github.com/shipilev/jdk/runs/1771453139?check_suite_focus=true

E: Could not configure 'libc6:i386'.
E: Could not perform immediate configuration on 'libgcc-s1:i386'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

It seems JDK-8259924 helped only for a while.

There is a [bugfix](https://salsa.debian.org/apt-team/apt/-/commit/998a17d7e6f834c341f198ca5b6df2f27e18df38) in Apt 2.0.4 that prints these warnings and then allows the whole thing to continue. It was [released](https://bugs.launchpad.net/ubuntu-cdimage/+bug/1871268) in Ubuntu a week ago, but it is not in base image yet. So, if we upgrade apt before installing other packages, apt updates from 2.0.2 to 2.0.4 and the whole thing starts to work.

This also reverts changes added by previous attempt in [JDK-8259924](https://github.com/openjdk/jdk/commit/a9519c83).
