Since netlink messages are in host byte order, shipping a pre-generated
nlmsg blob won't suffice on systems with different endianness. Therefore
generate the blob at runtime, so it's content fits the hosts endianness.
Note that the generated message will contain only a single interface
featuring two VFs instead of the full list before. Yet this is
sufficient, as it triggers the crash with iproute versions prior to
commit 8c29ae7cc2 ("ip link: Fix crash on older kernels when show VF
dev").

Added possibility to check command output by grep from the testing
script.
Now TMP_OUT & TMP_ERR are passed from Makefile and changed to
STD_ERR & STD_OUT.
Also changed some existing tests to make output testing.

Added two tests which checks the following fixed issues:
1) Bug when not possible add new virtual interface via:
$ ip link add dev XXX type
It was fixed a few releases ago.
2) Crash on older kernels when VF rate info does not exist:
$ ip link show
Used dump file from William Dauchy <william@gandi.net>:
testsuite/tests/ip/link/dev_wo_vf_rate.nl
So 'ip link show' replaced by 'ip -d monitor file ...' which does
the same thing.
Also added new func in testsuite/lib/generic.sh to gen new random dev name.
Added 'clean' dependency on running all tests.
