runtime(java): Dismiss "g:markdown_fenced_languages" for Java buffers

No support is provided or planned for language recognition
in code snippets of documentation comments.  Requesting to
load arbitrary syntax plugins with the aid of the concerned
variable is therefore wasteful in general and erroneous when
paired languages ":syn-include" one another without taking
steps to manage circularity.
