[PATCH 02/48] objtool/klp: Fix .data..once static local non-correlation

While there was once a section named .data.once, it has since been
renamed to .data..once with commit dbefa1f31a91 ("Rename .data.once to
.data..once to fix resetting WARN*_ONCE"). Fix it.

Fixes: dd590d4d57eb ("objtool/klp: Introduce klp diff subcommand for diffing object files")
