nettle: Add ptests

Use the nettle testsuite as ptests. Skip "sha1-huge-test" because
it can take 20 minutes to finish.

+Subject: [PATCH] Add target to only build tests (not run them)
+
+Not sending upstream as this is only a start of a solution to
+installable tests: It's useful for us already as is.
+
+Upstream-Status: Inappropriate [not a complete solution]
