[issue44762] getpass.getpass on Windows fallback detection is bad

[jan matejek]

jan matejek <ja+python at matejcik.cz> added the comment:

...this is a problem because:

When the check incorrectly infers that it can use `msvcrt` while its stdin is a pipe, the calls to `putwch` and `getwch` are going into the void and the program effectively freezes waiting for input that never comes.
