Get UPX working on x86 to decrease Docker image size for API

[joswayski]

Until Hetzner has ARM in the US, we have to build for AMD/x86. However this produces a MASSIVE YUGE dockerfile

;)

This is to see if we can reduce it, but right now we get an error when adding it in the packages/api (and consumer when added)

Acceptance Criteria:
Size is reduced from these figures for x86 builds
