test: widen oxlint contract and built-bin spawn budgets

Both suites spawn real subprocesses (oxlint probes; the dsh built bin) that
cold-start slowly on the contended self-hosted Windows pool, so their 20-25s
timeouts fire before the child finishes. Raise the oxlint contract case
timeouts to 60s and the built-bin execa timeouts to 60s, matching the
tool-ralph budget treatment.
