[PULL 04/12] configure: Add a proper check for sys/ioccom.h and use it in tpm_ioctl.h

[Thomas Huth]

On Solaris and Haiku, the _IO() macros are defined in <sys/ioccom.h>.
Add a proper check for this header to our build system, and make sure
to include the header in tpm_ioctl.h to fix a build failure on Solaris
and Haiku.
