[yaml2obj] Write the section header table after section contents

Linkers (ld.bfd/gold/lld) place the section header table at the very
end. This allows tools to strip it, which is optional in executable/shared objects.
In addition, if we add or section, the size of the section header table
will change. Placing the section header table in the end keeps section
offsets unchanged.

yaml2obj currently places the section header table immediately after the
program header. Follow what linkers do to make offset updating easier.
