Reid Kleckner c10f80eb7b [COFF] Update LLD yaml test cases to include .bss size 
These yaml test cases appear to have been affected by PR41836

Right now what happens is that these empty .bss sections are merged into
.data, then the .data output section ends up having a zero virtual size,
and it is discarded from the output after addresses are assigned.
However, we've already assigned OutputSections to Chunks, so we don't
correctly report the zero-sized chunks that were in there as having been
discarded. Soon, we will report them as discarded, so these test cases
need to be updated to have a non-zero size so they aren't discarded.
