[baremetal] prx: Fix empty Apache module list

On low state expansion, apache.server.modules is iterated, and
since reclass transforms '~' into 'null', an exception is thrown.

Use an empty string instead (different type will still ensure reclass
overrides variables from apache service instead of merging the lists).

While at it, add missing version 'latest' for mod-wsgi pkg.
