Another follow up to parser library loading issue

Browse Source 
Parser is present in both `runtime.jar` and `runner.jar` jars, leading
to shared library loading issues:
```
Caused by: java.lang.UnsatisfiedLinkError: Native Library <...>/component/libenso_parser.so already loaded in another classloader
    at java.base/jdk.internal.loader.NativeLibraries.loadLibrary(NativeLibraries.java:167)
    at java.base/jdk.internal.loader.NativeLibraries.loadLibrary(NativeLibraries.java:139)
    at java.base/java.lang.ClassLoader.loadLibrary(ClassLoader.java:2418)
    at java.base/java.lang.Runtime.load0(Runtime.java:852)
    at java.base/java.lang.System.load(System.java:2025)
    at org.enso.runtime/org.enso.syntax2.Parser.initializeLibraries(Parser.java:36)
    ... 43 common frames omitted
Caused by: java.lang.UnsatisfiedLinkError: Can't load library: <...>/target/rust/debug/libenso_parser.so
    at java.base/java.lang.ClassLoader.loadLibrary(ClassLoader.java:2422)
```

This change ensures that library is only loaded once.
