ELF may load debuginfo to get more symbols #2489

Description

Now the class ELF could load executables perfectly, but some symbols could not be found in libc.so.6 for optimization. However, these debug symbols are included in its debuginfo which could be downloaded via debuginfod on multiple distros. When I try to load the debuginfo so that I have more symbols to access, it failed, as it was detecting relro.

---> 19 libc = ELF('./lib/libc.debuginfo')
File /usr/lib/python3.12/site-packages/pwnlib/elf/elf.py:362, in ELF.__init__(self, path, checksec)
File /usr/lib/python3.12/site-packages/pwnlib/elf/elf.py:457, in ELF._describe(self, *a, **kw)
File /usr/lib/python3.12/site-packages/pwnlib/elf/elf.py:2069, in ELF.checksec(self, banner, color)
File /usr/lib/python3.12/site-packages/pwnlib/elf/elf.py:1702, in ELF.relro(self)
File /usr/lib/python3.12/site-packages/pwnlib/elf/elf.py:1604, in ELF.dynamic_by_tag(self, tag)
AttributeError: 'Section' object has no attribute 'iter_tags'

If the ELF class could pass these checks for debuginfo, more symbols could be grabbed.
