  [BOLT,test] Add --image-base to tests that use --section-start

When using -no-pie without a SECTIONS command, the linker uses the
target's default image base. If -Ttext= or --section-start specifies an
output section address below this base, the result is likely unintended.
LLD will give a diagnostic (#140187) and may change the behavior in the future.
It's good to set an explicit image base to avoid relying on its current
behavior. BOLT doesn't seem to care whether a PT_PHDR segment is
present.
