As of now, the usage of rpath is localised, so it is relatively easy
to evaluate the effect/prudence of such a change;  I am not so confident
in imposing rpath on all of the selftests (and, if doing so, I would
rather opt for runpath, to leave out an ability to override the search
path via LD_LIBRARY_PATH, if such need arises);  in that case it is possibly
also worth to add -L$(OUTPUT) to the CFLAGS as well, as the compile-time
counterpart.  But, again, I was trying to avoid the task of evaluating
the possible side effects of such a change, considering the variability
in environments and setups selftests are run.

I hesitated to do so due to the fact that different selftests are seemingly
maintained by different people.

I have checked the ldd output after the change remained the same (and that ldd
is able to find the libraries used when run outside the directory the tests
reside in) and did a cursory check of the results of the run of the affected
tests (but not so sure about the BPF selftests, as they don't compile as-is
due to numerous "incompatible pointer types" warnings that are forced
into errors by -Werror and the fact that it hanged the machine I tried
to run them on).
