perf symbols: Treat all memory maps without dso file as loaded

The stack/vdso/heap memory maps dont have any dso file.  Setting the
perf dso objects as 'loaded' for these maps, we avoid unnecessary
warnings like:

  "Failed to open [stack], continuing without symbols"

All map__find_* functions still return NULL when searching for symbols
in these maps.
