DLPX-92534 linux-pkg changes for LTS upgrade to 24.04

[palash-gandhi]

Problem

This PR contains changes required for the Ubuntu LTS upgrade to 24.04 and as such targets the os-upgrade branch. It mainly removes a few internal sources in favor of upstream packages and also enables building the remaining packages on 24.04.

Solution

The following are the changes, along with explanations for each:

1. bpftrace, bcc, drgn, fio, gdb-python, libkdumpfile and mold: All of these packages also can be sourced directly from their respective upstream sources (dependent changes WIP)
2. New kernel build parameters like do_dbgsym_package=True, do_tools_common=false and do_tools_host=false added with explanations.
3. llvm-12 is not available on 24.04. As such update connstat and zfs's build dependency to depend on llvm-14 instead.
4. adoptopenjdk: Prior to this PR, the JDK was sourced and downloaded from our internal artifactory. There is no reason to not install this via apt.
5. zfs also requires additional packages:
   • dh-dkms
   • libpam0g: The bootstrap image that the current + future OS upgrade projects will initially use is based on a vanilla Ubuntu image, and not a Delphix-based buildserver. Hence, the PAM headers need to be installed as a build dependency of ZFS
   • libtirpc-dev
6. Add mirror selection logic to select v2 mirrors for versions > 2025.2.

can you clarify why it's OK to remove the adoptopenjdk package? why did we need it to begin with?

From https://perforce.slack.com/archives/C07HB5Y7K8S/p1729097131001349, it sounds like it was an old process that we stuck to and there's no reason to maintain a copy of the package in artifactory.

Thanks, OK.. I'd defer to Seb, so if he's OK with it, then seems reasonable to me.. perhaps when we started down that path, there wasn't a JDK 8 available from ubuntu..
