VCL compiler creates non-compileable code when calling functions that takes zero arguments (patch attached)

[Martin Blix Grydeland]

The VCL compiler will produce code that does not compile when calling
functions that takes zero arguments (these would be imported from vmods as
none of the internal functions takes zero arguments). This because it will
always output a comma in preparation for the arguments. Attached is a patch
to correct this and only supply the comma when it is needed.
