Cleanup the msg_gen_function list in cfg.mk

Remove symbols that don't exist anymore (e.g. ERROR0) or aren't
message generating functions (e.g. VIR_FREE) or are now reported
as unmarked because the grep command is different, but that should
not be marked at all (e.g. DEBUG0).

Also don't restrict one of the grep lines in the
libvirt_unmarked_diagnostics rule to match exactly one space
between function name and opening parenthesis.
