LLVM's linker, LLD, supports the keyword "INSERT AFTER", starting with
version 11.
However, when multiple sections are defined in the same "INSERT AFTER",
they are added in a reversed order, compared to BFD's LD.
This patch makes fork_fuzz.ld generic enough to work with both linkers.
Each section now has its own "INSERT AFTER" keyword, so proper ordering is
defined between the sections added.
