[PATCH iproute2 v2 2/4] testsuite: declare dependency between $(TESTS) and generate_nlmsg

[Luca Boccassi <bluca@debian.org>]

Parallel make from the top level directory fails since tests are at the
same time as generate_nlmsg:

$ make check -j4

...

cd testsuite && make && make alltests
echo "Entering iproute2" && cd iproute2 && make configure && cd ..;
Entering iproute2
make -C tools
Removing results dir ...

Add an explicit dependency in testuite/Makefile's $(TESTS) rule so
that the tool correctly gets compiled before any test runs.
