[OE-core] [PATCH 1/1] classes/image: disable pam nullok_secure with debug-tweaks

[Paul Eggleton]

If you want passwordless logins to work with pam enabled, then you can't
have "nullok_secure" enabled on pam_unix entries. Add some
postprocessing to change these to "nullok" when debug-tweaks is in
IMAGE_FEATURES, in order to make passwordless logins with PAM work
again.

Fixes [YOCTO #5973].
