With CONFIG_LTO_CLANG, the compiler/linker adds .llvm.<hash> suffix to
local symbols to avoid duplications. Existing scripts/kallsyms sorts
symbols without .llvm.<hash> suffix. However, this causes quite some
issues later on. Some users of kallsyms, such as livepatch, have to match
symbols exactly.

Address this by sorting full symbols at build time, and let kallsyms
lookup APIs to match the symbols exactly.

The changes look good from the livepatching POV. For both patches,
feel free to use:

I made a quick glance over the code changes. They look sane. But I did
not check them deep enough to provide a valuable Reviewed-by ;-)
