[PATCH] docs: adjust for demise of scripts/create_config

[Paolo Bonzini]

The config-host.h, $TARGET-NAME/config-target.h, $TARGET-NAME/config-devices.h 
files
are now generated by configure_file() rather than scripts/create_config.  Adjust
the relevant paragraph in docs/devel/build-system.rst, and take the occasion to
fix a preexisting confusion of *.h vs *.mak.
