[baremetal] MaaS: Fix adding mcp.rsa.pub

Upstream salt-formula-maas change [1] gated applying "maas_sshprefs"
low state by `region.sshprefs` being declared in reclass, which is
not true for our model.
Mend our region.sls patch to pass mcp.rsa.pub to MaaS unconditionally.
This fixes baremetal SSH login with mcp.rsa.

While at it, fix duplicate SSH key upload on MaaS state retry.
