client: Make get_password() not echo with POSIX && !HAVE_GETPASS

Browse source 
getpass() is traditional Unix, but has been withdrawn from POSIX.  We
provide a replacement in case it's missing.  The one for Windows
suppresses echo, like getpass() does.  Implement that for POSIX.  The
other differences to getpass() remain.
