[PATCH] scripts/faddr2line: Set LANG=C to enforce ASCII output

[John Wang]

Force tools like readelf to use the POSIX/C locale by exporting LANG=C
This ensures ASCII-only output and avoids locale-specific
characters(e.g., UTF-8 symbols or translated strings), which could
break text processing utilities like sed in the script
