fixed bug in output of two-body Green functions

[tmisawa]

I fixed a bug where the two-body Green's function was being output even when not explicitly specified,
while trying to compute the three-, four-, and six-body Green's functions.

Pull Request Overview

This PR addresses the bug where the two-body Green's function was output unexpectedly during the computation of higher-order Green’s functions. Key changes include:

• Wrapping the file open operation for the two-body Green’s function in a conditional block.
• Similarly adding a conditional block to close the file pointer only when the condition is met.
• Removing a commented-out debug print statement.

• [nitpick] Consider adding an inline comment to explain why the file open operation is conditional on NCisAjtCkuAlvDC to improve code clarity and maintainability.

  if(X->Def.NCisAjtCkuAlvDC>0){

• [nitpick] It may be helpful to add a comment here to clarify that the file is only closed when it was opened under the NCisAjtCkuAlvDC condition, ensuring maintainability and clarity about the file handling logic.
