Enable port 18080

The commit [1] altered how sockets are created and inadvertently removed
the default port 18080. We use this port extensively in development.
The bmcweb documentation describes the port 18080 for this use. [2]
Adding back the default port 18080.

The commit [1] added meson build options for adding additional ports.
In attempting to enable port 18080 using that mechanism I ran into
various build errors when additional-ports has a value. I've corrected
the config/meson.build file to address those errors. These changes are
not necessary to re-enable port 18080 but worth fixing anyway.

Note: Meson defines arrays as containing strings so there is no
to_string() method for the array member. [3]
```
../../../../../../workspace/sources/bmcweb/config/meson.build:137:39: ERROR: Unknown method "to_string" in object <[StringHolder] holds [str]: '18080'> of type StringHolder.
```

Tested:
 - Started bmcweb from /tmp and was able to connect through port 18080.
   Log shows:
```
[DEBUG app.hpp:111] Got 0 sockets to open
[INFO app.hpp:150] Starting webserver on port 18080
```
