support/scripts/generate-gitlab-ci-yml: use large runners for defconfigs

defconfigs are very unlikely to successfully build on a small runner
because they build a kernel (and often a toolchain). They're also likely
to benefit a lot from the additional parallelism on larger runners.

For now, always build them on large runners. There may be some for which
even the large runners don't have sufficient disk space or memory, but
we'll solve that when it happens.
