Leave the ceilings as headroom rather than as a broom

Lowering the wheel ceiling to 1G a moment ago used it to force out what
no run needs any more. That is the eviction's job, and using the ceiling
for it risks dropping objects a build still wants the day this project
grows. Restored to 2G.

pip goes the other way: windows-latest now fills 472 MiB of its 500M,
which is close enough that a ceiling meant as headroom is not providing
any. One value covers the matrix, and the platforms at 285 MiB are not
affected by being allowed more.
