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

scripts/zfs-tests.sh:
	SINGLETESTFILE=$(basename "$SINGLETEST")
tests/zfs-tests/tests/functional/cli_user/zfs_list/zfs_list.kshlib:
	ACTUAL=$(basename $dataset)
	ACTUAL=$(basename $dataset)
tests/zfs-tests/tests/functional/cli_user/zpool_iostat/
	zpool_iostat_-c_homedir.ksh:
	typeset USER_SCRIPT=$(basename "$USER_SCRIPT_FULL")
tests/zfs-tests/tests/functional/cli_user/zpool_iostat/
	zpool_iostat_-c_searchpath.ksh:
	typeset CMD_1=$(basename "$SCRIPT_1")
	typeset CMD_2=$(basename "$SCRIPT_2")
tests/zfs-tests/tests/functional/cli_user/zpool_status/
	zpool_status_-c_homedir.ksh:
	typeset USER_SCRIPT=$(basename "$USER_SCRIPT_FULL")
tests/zfs-tests/tests/functional/cli_user/zpool_status/
	zpool_status_-c_searchpath.ksh
	typeset CMD_1=$(basename "$SCRIPT_1")
	typeset CMD_2=$(basename "$SCRIPT_2")
tests/zfs-tests/tests/functional/migration/migration.cfg:
	export BNAME=`basename $TESTFILE`
tests/zfs-tests/tests/perf/perf.shlib:
	typeset logbase="$(get_perf_output_dir)/$(basename \
tests/zfs-tests/tests/perf/perf.shlib:
	typeset logbase="$(get_perf_output_dir)/$(basename \

These are potentially Of Directories, where basename is actually
useful
