crypto/tls-cipher-suites: Produce fw_cfg consumable blob
Since our format is consumable by the fw_cfg device,
we can implement the FW_CFG_DATA_GENERATOR interface.
Example of use to dump the cipher suites (if tracing enabled):
$ qemu-system-x86_64 -S \
-object tls-cipher-suites,id=mysuite1,priority=@SYSTEM \
-fw_cfg name=etc/path/to/ciphers,gen_id=mysuite1 \
-trace qcrypto\*
