LOG: MachO,test: Test DWARF section's begin symbol

MCObjectFileInfo::initMachOMCObjectFileInfo creates DWARF sections with
a temporary label as the `Begin` symbol, different from other object
file formats' section symbol.

 #150574 caused a regression that removed the label for MCAsmStreamer,
which was caught by no test but a ystem-darwin/target-aarch64 specific diagnostics-dsym.test
