Remove debug-tweaks references

We no longer provide this feature, so remove documentation for it. In
most cases, we can replace occurrences of "debug-tweaks" by
"allow-empty-password empty-root-password allow-root-login
post-install-logging" to achieve what this feature previously enabled.

Subtle, but the default local.conf does not include
post-install-logging, so in parts where there is mention of the default
local.conf file, adjust the documentation to only mention the first
three above.

In the intro manual, instead of providing instructions that replace
EXTRA_IMAGE_FEATURES entirely, provide ones that append
EXTRA_IMAGE_FEATURES.
