systemd: import: expand $ZPOOL_IMPORT_OPTS correctly 

Turns out $ZPOOL_IMPORT_OPTS expands in a shell-like fashion,
yielding 'import' '-aN' '-o' 'cachefile=none' for an unset variable,
and 'import' '-aN' '-o' 'cachefile=none' 'word1' 'word2' for a
white-spaced one, but ${ZPOOL_IMPORT_OPTS} expands like "${Z_I_O}"
would in a shell, yielding 'import' '-aN' '-o' 'cachefile=none' ''
(empty) and 'import' '-aN' '-o' 'cachefile=none' 'word1 word2' (spaced)

Fixes eec5ba113e "dracut: 90zfs: respect
zfs_force=1 on systemd systems"
