The password backends check the password as a C string, so "\0junk" was checked as "" while its nonzero length passed the PermitEmptyPasswords check. RequestAuthentication now refuses any password with a NUL before the policy check and the backends. - test_RequestAuth_embeddedNulPasswordRejected puts the NUL first, last and mid-password, and checks the fake crypt still runs Issue: F-16096

wolfsshd refuses a password containing a NUL byte. The backends check
the password as a C string, so "\0junk" passed PermitEmptyPasswords no
and logged in to an account with an empty password.
new test covers a NUL first, last and mid-password.
