Revert "Use the setvmmaxmapcount initcontainer by default in E2E tests (

#1300)" (#1302)

This reverts commit fff1526.
This commit is breaking our E2E tests chain, which deploy a
PodSecurityPolicy by default. Any privileged init container will not
work.

I'll open an issue for a longer-term fix to properly handle this.
