perf tools: Mark split kallsyms DSOs as loaded

The maps__split_kallsyms() will split symbols to module DSOs if it comes
from a module.  It also handled some unusual kernel symbols after modules
by creating new kernel maps like "[kernel].0".

But they are pseudo DSOs to have those unexpected symbols.  They should
not be considered as unloaded kernel DSOs.  Otherwise the dso__load()
for them will end up calling dso__load_kallsyms() and then
maps__split_kallsyms() again and again.
