app/test: fix build with ring pmd but no bond pmd

  If the bonding pmd is disabled, all autotest associated with it should be
disabled. However, some of those tests also depended upon the ring PMD so
were placed in a block depending on that driver - and unfortunately that
driver alone. This caused build failures if the ring PMD was enabled but
the bonding PMD disabled, due to missing header files and driver libs.

This error can be reproduced by configuring DPDK using e.g.

  meson configure -Ddisable_drivers=net/[!r]* build

(which will disable all drivers not starting with "r"), and then building
using ninja.

Fix this by moving all link bonding autotests to the one block and putting
a second conditional check within that block for those also requiring the
ring PMD.

Fixes: 207b1c813f39 ("test: fix build without ring PMD")

Just a note.
Looking at the makefile counterpart, I can see that if we disable the
null driver, we would have an issue too.

I'm not actually seeing an error with it in meson builds. Running a quick
test using build parameter "-Ddisable_drivers=net/null" shows no errors, so
I think we may be ok here.

I would expect an issue at runtime, as the bonding driver test wants
to use null ports.
But yes, the build is fine.

Applied, thanks.
