LU-3264 tests: import ZFS pool which has file-based vdev

For "zpool import" command, if the -d option is not specified,
the command will only search for devices in "/dev". However,
for the pool which was created with file-based virtual device,
we need explicitly specify the search directory otherwise the
import command will not find the device.

LU-3318 llite: Always build 64bit ino internally

Always build 64bit ino internally except the client is mounted
with "32bitapi" option, so client will always use 64bit ino
internally. It will build 32bit ino, only if application requires
32 bit ino.
