Recreation of binaries on file changes in make file

[AustinAbro321]

Describe what should be investigated or refactored

Currently the make file builds lots of binaries needed for end to end tests. Instead of rebuilding binaries or zarf packages on each subsequent run we simply check if they are there. This saves time but can lead to testing on old binaries or packages if they have changed. It would be better if we dynamically recreated binaries or packages within make if anything changed.
For example:

• any go code changes should lead to re-build on make
• any changes to the init package or zarf agent should lead to a rebuild of the init package on make init-package
• any change to any of the example packages should lead to rebuild - ideally this could be done dynamically but if that's not doable I still believe hard coding the paths is worth it.
