Dmitri Shuralyov b2fd76ab8d test: migrate remaining files to go:build syntax
Most of the test cases in the test directory use the new go:build syntax
already. Convert the rest. In general, try to place the build constraint
line below the test directive comment in more places.

For #41184.
For #60268.
