rts/linker/Elf.c: add missing <dlfcn.h> include (musl support)

The change fixes build failure on musl:

```
rts/linker/Elf.c:2031:3: error:
     warning: implicit declaration of function 'dlclose'; did you mean 'close'? [-Wimplicit-function-declaration]
     2031 |   dlclose(nc->dlopen_handle);
          |   ^~~~~~~
          |   close
```
