sys-fs/zfs: update live ebuild

pass --localstatedir="/var", not /var/lib

otherwise pid files end up in /var/lib/run, which is wrong.
localstatedir is only used to define runstatedir

AC_SUBST([runstatedir], ['${localstatedir}/run'])

the following will change:

zed pid and state file location
(assuming /var/run is a symlink to /run)
/var/lib/run/zed.{pid,state} -> /var/run/zed.{pid,state}

zfs-list.cache.new will be temporary generated there.
