test: add sysfs test with empty sysfs directory

Create a sysfs test where /sys/class/nvme and /sys/class/nvme-subsystem don't exist, simulating the nvme_core module being unloaded. Ensure nvme_scan_topology() is successful and creates an empty tree. Signed-off-by: Caleb Sander Mateos <[email protected]>
