[pve-devel] [PATCH installer] install: set postfix config compatibility level to 3.6 to avoid warning

otherwise postfix will complain about using a backward compatible
config. since we don't seem to use anything that would be problematic
here anyway [1], just bump the version to avoid spamming the logs.

tested this on two nodes by adapting the config there and running
`postfix reload`. setting this to 3.6 meant no more warnings, going back
down to 2 would warn again.
