[Libvir] [PATCH] conftest: fix transposed size and count arguments to fwrite.

[Jim Meyering]

I noticed conftest fail and tracked it down to this:

	conftest: fix transposed size and count arguments to fwrite.
	* tests/conftest.c: Include <string.h> and <errno.h>.
	  Also include strerror in diagnostic.
