passwd: fix crashes for unencrypted passwords starting with 'x'.
...
When deciding where the previous hash should come from, is is
assumed that 'x' started strings all mean to look in shadow.
This is probably harmless in practice, since modern Linux still
use only hashes instead of raw passwords.
However, this is more robust, and more importantly, it is more
consistent with the previous check, which explicitly tests for
the string to be "x".

passwd: prevent segfault when running as root
...
When running as root, passwd attempts to compare the new password to
the old password, without having grabbed the old passwd.
This checks if the previous password hash was grabbed before comparing
it against the new password hash.
