New API: find_inode

Library's counterpart of the daemon's internal_find_inode command.

It writes the daemon's command output on a temporary file and parses it,
deserialising the XDR formatted tsk_dirent structs.

It returns to the caller the list of tsk_dirent structs generated by the
internal_find_inode command.
