We quetry the swtpm for TPM specification info that goes into the
certificate for the EK.
Update the test cases that now see more capabilties being returned
by the swtpm.

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.

Copy the test case that use 'swtpm chardev' to test_ctrlchannel4
and convert this test in test_ctrlchannel to use a socket. Make
test_ctrlchannel run on all platforms. test_ctrlchannel4 only
runs when WITH_CHARDEV is set in the Makefile.
