[yaml2obj] Simplify p_filesz/p_memsz computing

This fixes a bug as well. When "FileSize:" (p_filesz) is specified and
different from the actual value, the following code probably should not
use PHeader.p_filesz:

  if (SHeader->sh_offset == PHeader.p_offset + PHeader.p_filesz)
    PHeader.p_memsz += SHeader->sh_size;
