Benjamin Gilbert 0f8b50a789 sys-block/open-iscsi: drop iscsidev.sh
The script and udev rule were added to Gentoo due to
https://bugs.gentoo.org/556632 without much explanation. However,
iscsidev.sh has multiple problems:

- It doesn't run for all iSCSI devices, only those with a vendor string
of "IET". Thus it works for e.g. tgtd but not for enterprise iSCSI
targets.

- It was added in 2015, but udev's builtin path_id has supported iSCSI
targets -- and produced exactly the same /dev/disk/by-path links --
since systemd/systemd@a2fe9450bb in 2009.

- When the script decides not to do anything, it exits 1, producing a
series of systemd-udevd journal messages:

    systemd-udevd[636]: Process '/usr/lib/udev/scripts/iscsidev.sh' failed with exit code 1.
