all: fix build timeouts for std dependent snippets

This change addresses two issues that were causing the first build of a
snippet to be unusually slow.

One is to build the standard library with faketime, and CGO_ENABLED=0 in
our final container, which is more similar to our actual build
environment. This fixes staleness issues from std.

Another is to pre-vet std with --tags=faketime. The first vet of a
snippet that contained a significant std package such as net/http would
take 5-6 seconds, and frequently longer than our maxBuildTime of 10s.

Finally, execute vet with the correct tags when a user is vetting their
snippet.

Fixes golang/go#44822
