After reverting the last commit on plugins/meson.build the build succeeds, because here the parameter causing the failure (`--dynamic-list`) is only applied, if plugins are enabled.

meson: merge plugin_ldflags into emulator_link_args
These serve the same purpose, except plugin_ldflags ends up in the linker
command line in a more roundabout way (through specific_ss). Simplify.

```
Configuring with plugins enabled fails with:
```
