наб d09e1c1343 libzutil: zfs_isnumber(): return false if input empty
zpool list, which is the only user, would mistakenly try to parse the
empty string as the interval in this case:

  $ zpool list "a"
  cannot open 'a': no such pool
  $ zpool list ""
  interval cannot be zero
  usage: <usage string follows>
which is now symmetric with zpool get:
  $ zpool list ""
  cannot open '': name must begin with a letter

Avoid breaking the  "interval cannot be zero" string.
There simply isn't a need for this, and it's user-facing.
