meson: list leftover CONFIG_* symbols

There are no config-host.mak symbols anymore that are needed in
config-host.h; the only symbols that are included in config_host_data via
the foreach loop are:

- CONFIG_DEFAULT_TARGETS, which is not used by C code.

- CONFIG_TCG and CONFIG_TCG_INTERPRETER, which are not part of config-host.mak

So, list these two symbols explicitly.
