Currently lx-symbols assumes that module text is always located at
module->core_layout->base, but s390 uses the following layout:
+------+ <- module->core_layout->base
| GOT |
+------+ <- module->core_layout->base + module->arch->plt_offset
| PLT |
+------+ <- module->core_layout->base + module->arch->plt_offset +
| TEXT | module->arch->plt_size
+------+
Therefore, when trying to debug modules on s390, all the symbol
addresses are skewed by plt_offset + plt_size.
Fix by adding plt_offset + plt_size to module_addr in
load_module_symbols().
