package/openssh: security bump to version 8.8p1

Fix CVE-2021-41617: sshd in OpenSSH 6.2 through 8.x before 8.8, when
certain non-default configurations are used, allows privilege escalation
because supplemental groups are not initialized as expected. Helper
programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may
run with privileges associated with group memberships of the sshd
process, if the configuration specifies running the command as a
different user.
