fix(nmrih): add if statements for symlink fixes

This commit fixes an issue where certain server files were missing. Symbolic links are now created for the following files if they do not already exist: vphysics.so, studiorender.so, soundemittersystem.so, shaderapiempty.so, scenefilecache.so, replay.so, and materialsystem.so.
