qapi/pragma: Tidy up after removal of deprecated commands

Commit cbde7be9 "migrate: remove QMP/HMP commands for speed,
downtime and cache size" neglected to remove query-migrate-cache-size
from pragma returns-whitelist.

Commit 8af54b91 "machine: remove 'query-cpus' QMP command" neglected
to remove CpuInfo & friends from pragma name-case-exceptions.

Remove these now.
