feat: switch back default to static binding of binaries (#184)

[tkrop]

This pull request switches the default behavior to CGO_ENABLED=0 for static binding. This was used before in binary build for images, while binaries build for local execution usually have been build using CGO_ENABLED=1 for smaller size and to speed up building. After unifying the build process, this distinction is not any longer available and we need to decide for a default and static binding seems to be less error prone.
