[TCTI/ESYS] Enable building on VxWorks

This patch allows building on VxWorks by:
- Adding the VXWORKS makro to several places
- Pointing to a different location for poll.h on VxWorks (i.e. sys/poll.h)
- Pointing to /tpm0 instead of /dev/tpm0 for the device node (ESYS and TCTI)
- Using a 3-parameter version of open() despite O_CREAT.
VxWorks does not support a 2-parameter version. It will also check
file-permissions vs the third parameter of open().
