objtool/klp: Handle Clang .data..Lanon anonymous data sections
Clang generates anonymous data sections named .data..Lanon.<hash>.
These need section-symbol references in the same way as .data..Lubsan
(GCC) and .data..L__unnamed_ (Clang UBSAN) sections. Without this,
convert_reloc_sym() fails when processing relocations that reference
these sections.
