[WebAssembly] Fix R_WEBASSEMBLY_FUNCTION_OFFSET_I32 relocation entries
Fixes: lld: warning: unexpected existing value for R_WEBASSEMBLY_FUNCTION_OFFSET_I32: existing=839 expected=838
The existing solution is trying to erroneously recover correct offset of
the function code from the body (which is not a function segment that
includes its size, locals, and code).
The D46763 is trying to maintain the offset of the function code
allowing properly calculate the new relocation entry.
