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.
