Update the libbpf submodule to the latest version, and update the configure
script so we check for the newer bpf_object__next_program() helper (to fix
deprecation warnings).

This allows including Makefile to define USER_TARGETS_OBJS
that contain code that USER_TARGETS depend on and needs
to be compiled as objects and later linked with.

Seems some distributions will change the clang version output to be
something like 'Ubuntu clang version
12.0.1-++20210918042554+fed41342a82f-1~exp1~20210918143322.141'. Fix the
version parsing in configure to not barf on such weird version strings.

Use a JSON-writer library from iproute instead of complicated printf
statement. Also output timestamp, rtt and min_rtt as integers in
nanoseconds, rather than floats in seconds.

Add the directory and Makefile rules to prepare for storing library
functions in lib/util like we do in xdp-tools. With this, library code can
be added by just dropping the .c and .h into lib/util and updating
lib/util/util.mk with the object name.

This updates the libbpf submodule to the latest upstream version, which
notably includes the new API for directly attaching TC programs without
shelling out to the 'tc' binary.

The wildcards picking up header files only included specific subdirectories
of include/ and headers/. There are actually files in multiple subdirs,
though, so just expand the wildcard to include all subdirectories to make
sure objects are rebuilt properly.

When installing libbpf headers into 'lib/libbpf/src/root/' then the git
submodule for libbpf is marked dirty. This result in stgit complains under
different operations.
This patch fix the issue by installing libbpf outside submodule directory.
Choose directory 'lib/libbpf-install/' to emphasize relation to 'lib/libbpf/'.
V2: Don't install the library only the header files as before. Also
installing the should be a separate commit. Patch still statically
link with libbpf/src/libbpf.a.
