[DOC] Remove --scpopt and --sshopt in Innobackupex options list

[Jericho Rivera]

Both options --scpopt and --sshopt can still be found on Xtrabackup 2.1 and 2.2 innobackupex options list. AFAIK, these options were removed since --remote-host option was deprecated.

That's all we can see about these options in recent enough code:

storage/innobase/xtrabackup/doc/source/release-notes/2.0/1.9.1.rst:41: * When using --remote-host to a non-standard SSH port, the |xtrabackup| wasn't passing the correct port to both ssh and scp, which use different options for port number (-p vs -P). It's now possible to pass custom SSH options to innobackupex, such as a non-standard port, with the --sshopt option. Bug fixed: :bug:`733658` (*Sergei Glushchenko*).

The same is still present in 2.3 and 2.4 documentation as well as in the man page:
 man innobackupex|
       --scpopt = SCP-OPTIONS

Fragment from https://www.percona.com/doc/percona-xtrabackup/2.4/innobackupex/innobackupex_option_reference.html

" --scpopt = SCP-OPTIONS

    This option accepts a string argument that specifies the command line options to pass to scp when the option --remost-host is specified. If the option is not specified, the default options are -Cp -c arcfour"
