[utils] use select instead of poll to read passphrases on macOS

Browse Source 
According to the man page on macOS poll currently doesn't support
devices. This includes `/dev/tty`.
In this use case poll will returned immediately indicating that
something can be read but the following read returned `-1`
(with errno set to EAGAIN).

Using select on macOS for passphrase reading prevents this problem.
