cluster: add '=' to ssh pubkey pattern

ssh public keys are base64 encoded, thus can potentially contain =.
until now the RSA keys generated by Debian were 2048 bits long and did
not need padding

with bullseye (openssh (1:8.0p1-1)) the RSA keysize got increased to
3072 bits, and now does contain a =

noticed while trying to join a PMG container from a bullseye template
to my existing cluster (the error happens on the new node).
