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

[Petr Vorel]

Hi Wei,

I suppose the v1 is
https://patchwork.ozlabs.org/project/ltp/patch/20240918100344.21316-1-wegao@suse.com/

To be honest, I would rather to remove this FTP test because FTP protocol is
legacy. I know it is supposed to be a smoke test, but maybe using modern tools
would be better than keeping test working among various old FTP implementations.
(Also nontrivial setup is required just for few FTP tests:
https://github.com/linux-test-project/ltp/tree/master/testcases/network )
But probably Cyril would be against. @Cyril @Martin WDYT?

@Wei I suppose the reason for adding lftp (you did not explain it in the commit
message) is that is the only supported client in SLE Micro? Or something else?

Test was converted to the new API, it must be tst_brk.
Also, this code basically means that testing is done only for lftp,
otherwise TCONF.
+ You keep requiring ftp in TST_NEEDS_CMDS, but at least on Tumbleweed and
current Debian testing lftp does not provide symlink to ftp, only tnftp does
this. Therefore you require both lftp and tnftp for testing.

Kind regards,
Petr
