MFV r316872: 7502 ztest should run zdb with -G (debug mode)

  Right now ztest executes zdb without -G, so when it has errors, the messages
  are often not very helpful:
  Executing zdb -bccsv -d -U /rpool/tmp/zpool.cache ztest
  zdb: can't open 'ztest': Operation not supported
  ztest: '/usr/sbin/amd64/zdb -bccsv -d -U /rpool/tmp/zpool.cache ztest' exit
  code 1
  With -G, we'd have:
  /usr/sbin/amd64/zdb -bccsv -d -U /rpool/tmp/zpool.cache -G ztest
  zdb: can't open 'ztest': Operation not supported

  ZFS_DBGMSG(zdb):
  spa_open_common: opening ztest
  spa_load(ztest): LOADING
  spa_load(ztest): FAILED: unable to parse config [error=48]
  spa_load(ztest): UNLOADING
  Which indicates where the error came from
