tmp: run file-ft-tests-null-compat 10x for CLDSRV-992 flakiness validation

Fans the null-compat matrix out to 10 parallel copies. Keeps kmip-ft-tests,
kmip-cluster-ft-tests and sse-kms-migration-tests enabled so a readiness gate
that never opens shows up as a hang. Dropped before review. Precedent: a3847d6.
