[PATCH v1 1/1] virt: acrn: Drop internal kernel type from ABI

[Andy Shevchenko]

guid_t is internal type of the kernel which is mistakenly had been exposed
to the user space. Replace it with raw buffers.

Besides that it's obvious from the link in the sample code, that the real
use is of uuid_t type, but because uuid_t hasn't exposed, so should guid_t,
the code includes and uses wrong type.

Fixes: 5b06931d7f8b ("sample/acrn: Introduce a sample of HSM ioctl interface usage")
Fixes: 9c5137aedd11 ("virt: acrn: Introduce VM management interfaces")
