cmd/link: fix coverage counter issue on AIX

Browse Source 
Update the linker's XCOFF writer to handle coverage counter sections
properly; they need to be treated as bss, not data. Fixes a problem
with the aix-ppc64 builder introduced in CL 401235), e.g.
"runtime.covctrs: A symbol with type XTY_SD must be in a .text or
.data section".

Updates #51430.
