ivshmem-test: Clean up wait for devices to become operational
test_ivshmem_server() waits until the first byte in BAR 2 contains the
0x42 we put into shared memory. Works because the byte reads zero
until the device maps the shared memory gotten from the server.
Check the IVPosition register instead: it's initially -1, and becomes
non-negative right when the device maps the share memory, so no
change, just cleaner, because it's what guest software is supposed to
do.
