docs: sysrepo install-prefix since cmake 3.21

use the new recommendation from cmake:
  --install-prefix <directory>
     New in version 3.21.

     Specify the installation directory, used by the
     CMAKE_INSTALL_PREFIX variable. Must be an
     absolute path.

reminder: the default path is /usr/local instead of /usr
