The relative RPATH ("./") supplied to linker options in CFLAGS is resolved
relative to current working directory and not the executable directory,
which will lead in incorrect resolution when the test executables are run
from elsewhere. Changing it to $ORIGIN makes it resolve relative
to the directory in which the executables reside, which is supposedly
the desired behaviour.
Discovered by the /usr/lib/rpm/check-rpaths script[1][2] that checks
for insecure RPATH/RUNPATH[3], such as containing relative directories,
during an attempt to package BPF selftests for later use in CI:
ERROR 0004: file '/usr/libexec/kselftests/bpf/urandom_read' contains an insecure runpath '.' in [.]

Wouldn't make sense to fix fix this in selftests main Makefile
instead of changing the all the test makefiles
Same comment on all other files. It would be easier to send
these as series - please mentioned the tests run as well
after this change.
thanks,
