Remove basename(1). Clean up/shorten some coreutils pipelines
Basenames that remain, in cmd/zed/zed.d/statechange-led.sh:
	dev=$(basename "$(echo "$therest" | awk '{print $(NF-1)}')")
	vdev=$(basename "$ZEVENT_VDEV_PATH")
I don't wanna interfere with #11988

These are potentially Of Directories, where basename is actually
useful

# Send notification in response to a given zevent.
#
# This is a generic script than can be symlinked to a file in the
# enabled-zedlets directory to have a notification sent when a particular
# class of zevents occurs. The symlink filename must begin with the zevent
# (sub)class string (e.g., "probe_failure-notify.sh" for the "probe_failure"
# subclass). Refer to the zed(8) manpage for details.
#
# Only one notification per ZED_NOTIFY_INTERVAL_SECS will be sent for a given
# class/pool combination. This protects against spamming the recipient
# should multiple events occur together in time for the same pool.
#
# Exit codes:
# 0: notification sent
# 1: notification failed
# 2: notification not configured
# 3: notification suppressed
