GHA/linux: enable wolfSSH in a wolfSSL job

With tests. (Most SFTP tests fail with wolfSSH.)

Also:
- disable pseudo-terminal in wolfSSH builds (also in CircleCI).
  Not needed for curl.
- test642: add "compressed" to the description.
  To avoid being the same as test600.
  Follow-up to b7b4dc0 curl#1735

Closes curl#16025
