It was clear that hard-coded section names aren't reliable enough but
they broke down way earlier than has been expected.
This patch replaces hard-coded sections with a loop, scanning all
sections and selecting them based on their flags and types.

Always use a "raw string" for regular expressions, otherwise the
backslash is used to start Unicode escape sequences.
Fixes hopefully harmless error:
```
scripts/llext_link_helper.py:38: SyntaxWarning: invalid escape sequence '\.'
p = re.compile('(^lib|\.so$)')
```

When an ELF section isn't found .get_section_by_name() raises an
AttributeError exception, catch it specitically instead of catching
any exception.

Add support for relocatable objects to the llext module build system.
In such builds no ELF segments are created, so we need to process all
sections individually.
