selftests/bpf: Adapt OUTPUT appending logic to lower versions of Make
The $(let ...) function is only supported by GNU Make version 4.4 [0]
and above, otherwise the following exception file or directory will be
generated:
tools/testing/selftests/bpfFEATURE-DUMP.selftests
tools/testing/selftests/bpffeature/
Considering that the GNU Make version of most Linux distributions is
lower than 4.4, let us adapt the corresponding logic to it.
