llvm: Upgrade to LLVM 17.0.6

Fixes for Clang 17 were merged into the Cilium codebase:

b91046955d6b ("datapath: Ignore new debug ELF prefixes")
6e18eb020b68 ("bpf: Fix compatibility with Clang 17 in __lb6_affinity_backend_id")
3740e9db8fef ("bpf: Fix "R2 !read_ok" verifier error with LLVM 17")
c6fe6b8e2546 ("bpf/tests: Fix `conntrack_test.c` in prep for Clang update")
4dd6b0a4f97f ("bpf/tests: Fix undefined behavior in memcmp MAC addresses")
f87b5dc5e0b2 ("bpf/tests: Fix undefined behavior in EXPECTED_DEST_MAC")

and the complexity measurements were performed, so now the LLVM image
can be upgraded.
