Polish netmap(4) testcases a bit

1. Not all kernels have netmap(4) support. Check for netmap(4) support before
   attempting to run the tests via the `PLAIN_REQUIRE_KERNEL_MODULE(..)` macro.
2. Libraries shouldn't be added to LDFLAGS; they should be added to LIBADD
   instead. This allows the build system to evaluate dependencies for sanity.
3. Sort some of the Makefile variables per bsd.README.

1., in particular, will resolve failures when running this testcase on kernels
lacking netmap(4) support, e.g., the i386 GENERIC kernels on ^/stable/11 and
^/stable/12.

In this cases it is desirable to have more than a pair of RX/TX host rings, and use multiple threads to speed up forwarding. This change adds support for multiple host rings. On registering a netmap port, the user can specify the number of desired receive and transmit host rings in the nr_host_tx_rings and nr_host_rx_rings fields of the nmreq_register structure.

netmap: add suite of unit tests

Import the unit tests from upstream (https://github.com/luigirizzo/netmap
ba02539859d46d33), and make them ready for use with Kyua.
There are currently 38 regression tests, which test the kernel control ABI
exposed by netmap to userspace applications:

  1: test for port info get
  2-5: tests for basic port registration
  6-9: tests for VALE
  10-11: tests for getting netmap allocator info
  12-15: tests for netmap pipes
  16: test on polling mode
  17-18: tests on options
  19-27: tests for sync-kloop subsystem
  28-39: tests for null ports
  31-38: tests for the legacy NIOCREGIF registers
