setup-build-env: install llvm development package

Recently kernel BPF selftests gained an optional dependency on LLVM development libraries [1] in order to support tests that disassemble jit produced code. When necessary dependencies are not available such tests are skipped. This commit adds LLVM development libraries to the build environment, thus enabling jit disassembly tests on the CI.
