[PATCH] meson: Require libssh-0.8.0 or newer

[Michal Privoznik]

According to repology.org:

              RHEL-8: 0.9.4
              RHEL-9: 0.9.6
           Debian 11: 0.9.5
  openSUSE Leap 15.3: 0.8.7
        Ubuntu 20.04: 0.9.3

And the rest of distros has something newer anyways. Requiring
0.8.0 or newer allows us to drop the terrible hack where we
rename functions at meson level using #define.  Note, 0.8.0 is
the version of libssh where the rename happened.
