Update make.conf for caddy-custom build to mitigate build errors (#397)

* Update make.conf

As explained here:
Monviech/os-caddy-plugin#102

Change the priority to desec and porkbun instead of vultr, since they have been especially requested in past issues of os-caddy-plugin.

The issue stems from vultr having different libdns dependencies than the other modules, making the build fail if it's included with certain other combinations of modules (e.g. desec).

* Update make.conf

Remove mention of vultr, will be tracked independently if its fixed in the future
