fix spwaning process bug in automatic eden doctor run

Summary:
# problem
`eden doctor` automatic run is failing with below error-
```
EI1015 00:18:55.202938 116940 EdenServer.cpp:2767] Running periodic eden doctor dry-run.
E1015 00:18:55.203525 116940 SpawnedProcess.cpp:706] class std::system_error: CreateProcess("edenfsctl" "doctor" "--dry-run") failed with cwd: (no cwd provided), creation flags: 0, execPath: (no execPath provided): Error (0x57) The parameter is incorrect.
```

# solution
This is similar to D59783277.
We need to pass SpawnedProcess options while spawning a process with default params.
