adds upx compression to our biggest bins in builder-base

[jaxesn]

Issue #, if available:

Description of changes:

@abhay-krishna suggested we see what happens if we use upx to compress some of our larger bins, esp the golang statically compiled ones. I gave it a shot and actually it does add pretty decent savings in terms of space, esp on the decompressed final image, it ends up going from ~3.8GB to ~2.4GB. Some of this is from the python and golang cleanup i am also doing here, but a good chunk is the upx compression. The download size savings is probably 300-400MB, just per the ECR ui in my dev account.

I have tested this by building all of the eks-a stack. I feel pretty good that that compressed binaries do not cause any issues...
