cmd/link/internal/ld: more fixes to TestElfBindNow readonly .got check
Second try at fixing the TestElfBindNow testpoint: don't try to check
for readonly ".got" section when using the external linker, since
there is code in some linkers (BFD in particular) that will skip
placing ".got" in relro if the section is below a specific size
threshold. Revised version of the test checks only for readonly
".dynamic" in the external linking case.
Fixes #67063.
