  [gold] Switch section-ordering-file tests to use ld.bfd (#219150)

ld.bfd supports `--section-ordering-file` since 2.43. Use it if the
binutils version is sufficiently recent.

The implementation in ld.bfd is significantly different, with the
section ordering file looking more like an incomplete linker script,
rather than a plain section listing.

The addresses of the sections are also slightly different than with
ld.gold. Use hex matches + arithmetic to just check the correct
order/offsets instead of hardcoding the exact choice of address.

ld.bfd also supports --start-lib/--end-lib since 2.47, but it seems like
those don't actually work with linker plugins, so I'm not migrating them
(https://sourceware.org/bugzilla/show_bug.cgi?id=34572).
