Fixes #322

@AdianKozlica I think this might be a potentially exciting addition.

Can you please add more detail to the PR description? Make sure to list:

• What the problem was
• If this was a bug or a missing feature
• How you addressed it, include design decisions made - justify adding additional services/programs to the WinBoat guest vs extending existing
• Include any screenshots/recordings demonstrating the fix

Additionally please add comments/documentation in the new (go) code explaining briefly what it does

Hello, so basically xfreerdp replaces the old instance of an app with a new one if the cli arguments are the same.

We can bypass this if we use a wrapper executable that has a dummy argument (in our case we use a random UUID).

Below is an example without the wrapper executable:

without-rdp_exec.mp4

And below is the example with the wrapper:

with_rdp_exec.mp4
