udev: Use $name in issuegen rule

A user is trying to rename network interfaces. This is working but the login issue file still has the initial network interface names. This appears to be similar to thkukuk/issue-generator#6, fix it by using $name instead of $ENV{INTERACE}, so that the rule runs with a changed name.

How to use

Testing done

Ran a qemu vm with the following udev rules:

# cd /etc/udev/rules.d
# cat 60-net.rules
SUBSYSTEMS=="pci", ACTION=="add", DRIVERS=="?*", KERNELS=="0000:00:03.0", NAME="ge0"
# cat 90-issuegen.rules
ACTION=="add", SUBSYSTEM=="net", ENV{INTERFACE}=="e*", RUN+="/usr/lib/flatcar/issuegen add $name"
ACTION=="remove", SUBSYSTEM=="net", ENV{INTERFACE}=="e*", RUN+="/usr/lib/flatcar/issuegen remove $name"

issue is correct:

Does that also work when the interface name is set from a networkd unit?

Yes, i just tested this now. Without this branch renaming from a networkd unit has the same bug. Fixed with this change.
