Implement a command for setting and querying the buffer size the TPM implementation (libtpms) is using. The setting of the buffersize allows to reduce the size of the buffer to a size that the interface can support so that these two sizes match and the TPM will not produce larger responses than what the interface can support. Extend swtpm_ioctl with an option to set the buffersize. Adapt the existing tests to reflect the newly supported command. Implement a new test for getting/setting of the buffer size.
