  [Bug]: src/system/os.py does not correctly return architecture for bsd platform
  ### Describe the bug
  
  
  Run `uname -m` will return follow in the freebsd:
  ```
  amd64
  ```
  
  The code here does not support `amd64` as input:
  https://github.com/opensearch-project/opensearch-build/blob/main/src/system/os.py#L12-L19
  ```
  def current_architecture() -> str:
      architecture = subprocess.check_output(["uname", "-m"]).decode().strip()
      if architecture == "x86_64":
          return "x64"
      elif architecture == "aarch64" or architecture == "arm64":
          return "arm64"
      else:
          raise ValueError(f"Unsupported architecture: {architecture}")
  ```
  
  
  
  Thanks.
  
  
  ### To reproduce
  
  Run the build process on a freebsd server and see output:
  ```
  $ ./build.sh manifests/2.4.0/opensearch-2.4.0.yml --component OpenSearch
  Installing dependencies in . ...
  Installing dependencies from Pipfile.lock (b36c9c)...
  To activate this project's virtualenv, run pipenv shell.
  Alternatively, run a command inside the virtualenv with pipenv run.
  Running ./src/run_build.py manifests/2.4.0/opensearch-2.4.0.yml --component OpenSearch ...

    File "./src/run_build.py", line 55, in main

    File "/usr/share/opensearch/opensearch-build/src/build_workflow/build_target.py", line 45, in __init__
      self.architecture = architecture or current_architecture()
    File "/usr/share/opensearch/opensearch-build/src/system/os.py", line 20, in current_architecture
      raise ValueError(f"Unsupported architecture: {architecture}")
  ValueError: Unsupported architecture: amd64
  
  ```
  
  ### Expected behavior
  
  The bsd x64 hosts can run the code without specifying --architecture x64.
  
  ### Screenshots
  
  If applicable, add screenshots to help explain your problem.
