INSTALL.md: add clang and llvm for install build dependence packages

clang and llvm are not default package of Ubuntu. So, add clang and
llvm for install build dependence packages on INSTALL.md file.

I've tested only on Ubuntu 24.04 but add dependence on every versions

You will encounter this error messages without this patch during
following steps.

  $ git clone https://github.com/iovisor/bcc.git
  $ mkdir bcc/build; cd bcc/build
  $ cmake ..
  $ cd ../libbpf-tools
  $ make profile
  ... snip ...
    BPF      profile.bpf.o
  /bin/sh: 1: clang: not found

  or

    BPF      profile.bpf.o
  /bin/sh: 3: llvm-strip: not found
