perf kcore_copy: Fix module map when there are no modules loaded
[ Upstream commit 61f82e3fb697a8e85f22fdec786528af73dc36d1 ]
In the absence of any modules, no "modules" map is created, but there
are other executable pages to map, due to eBPF JIT, kprobe or ftrace.
Map them by recognizing that the first "module" symbol is not
necessarily from a module, and adjust the map accordingly.
