Rather than creating stubs for every command that just return
QERR_UNSUPPORTED, use 'if' conditions in the QAPI schema to
fully exclude generation of the commands on non-Linux POSIX
platforms

The command will be rejected at QMP dispatch time instead,
avoiding reimplementing rejection by blocking the stub commands.

This has the additional benefit that the QGA protocol reference
now documents what conditions enable use of the command.
