[PATCH bpf-next 3/3] selftests/bpf: say how to fix the missing LLVM skip for jited checks

[Wang Yibo <szwyb123@gmail.com>]

When test_progs is built without LLVM development libraries, every
subtest that checks jited output is skipped with only "tests are built
w/o LLVM development libs" visible under -v. The message does not say
that installing the libraries and rebuilding is all that is needed, and
the verbose-only message in jit_disasm_helpers.c is missing a trailing
newline, so it runs together with the following output.

Mention the fix in the skip message and add the newline.
