LOG: DebugInfo: Simplify debug-macinfo-split-dwarf.ll

This test didn't need any local variables or parameters, and didn't need
to be checking the DWO ID or more detailed forms.

It was using -v to print the macro sections, but now that macro sections
are emitted when requested (-debug-macro) that's not needed either.
