btf: ungate resolve_btfids linker-flag fix for all android12-5.10
Drop the sublevel>43 gate from the 0002 patch step. On sublevel-43 trees
resolve_btfids links with 'clang $(LDFLAGS)' where LDFLAGS is undefined, so
clang falls back to default 'ld' which is absent in the pure-LLVM/Neutron
toolchain ('Executable "ld" doesn't exist'). Patch 0002 sets
LDFLAGS := $(KBUILD_HOSTLDFLAGS), which carries -fuse-ld=lld from the build
env (build/_setup_env.sh exports HOSTLDFLAGS, top Makefile exports
KBUILD_HOSTLDFLAGS), making clang link with ld.lld.
