Add Makefile accidentally missed in r292317

r292323:

Integrate tools/regression/lib/libc/nss into the FreeBSD test suite as
lib/libc/tests/nss

- Convert the testcases to ATF
- Do some style(9) cleanups:
-- Sort headers
-- Apply indentation fixes
-- Remove superfluous parentheses
- Explicitly print out debug printfs for use with `kyua {debug,report}`; for
  items that were overly noisy, they've been put behind #ifdef DEBUG
  conditionals
- Fix some format strings

Iterate down lib/libc/tests/nss...

r292665:

Increase the timeout for resolv_test from the default (300 seconds) to
450 seconds

This is required on slower network connections, and on older releases
(stable/10 seems to be slower as far as name resolution goes.. not sure
why yet).

Remove an outdated comment in the Makefile from when I was working on
this code over a year ago on github
