Fix broken build dependency, when compiling without perfschema

libfmt must be built before sql or sql_embedded target, since compilation
of item_strfunc.cc depends on it.

Previously, GenServerSource depended on libfmt,yet this GenServerSource
is not a  direct or indirect dependency of sql, if -DPLUGIN_PERFSCHEMA=NO
is used in cmake configuration step.
