udev: make udevadm test and test-builtin not destructive

Browse Source 
Previously, 'udevadm test' performs not only processing udev rules,
but made several destructive change on the system; updating udev
database, device node permission, devlinks, network interface
properties, and so on.

Similary, 'udevadm test-builtin' may perform something destructive,
especially by 'keyboard', 'kmod', and 'net_setup_link' builtins.

Let's make these commands and test executables not change device
configurations.
