Build stacker on Ubuntu 24.04 LTS (noble)

[raharper]

Fix build on Ubuntu 24.04

• install libsystem-dev for static libsystemd library
• Use ppa:puzzleos/dev to pull in patched lxc 5.0.3 which includes liblxc.a in the lxc-dev package
• Handle modifying kernel tunables for user-namespace and apparmor restrictions
• Adjust Makefile to add -lsystemd to the libs when making stacker-dynamic, but omit the library when stacker-static is building built
• Add default container policy to rfs if not already present
