[LTP] [PATCH v2] ftp01.sh: Add support for test lftp

[Petr Vorel]

Hi Wei, all,

first, please wait little bit before sending next version.
We might decide to remove these tests.
Below are notes in case we keep them.

Yes, this would work.

IMHO no. TST_NEEDS_CMDS should not contain ftp. On Tumbleweed with lftp
installed there is no ftp symlink:

$ lftp --version
LFTP | Version 4.9.2 | Copyright (c) 1996-2020 Alexander V. Lukyanov
...

$ ftp

The program 'ftp' can be found in following packages:
  * ftp [ path: /usr/bin/ftp, repository: OSS ]
  * tnftp [ path: /usr/bin/ftp, repository: OSS ]

Try installing with:
    sudo zypper install <selected_package>

Kind regards,
Petr
