utils_test: add osmo_print_n_test()

A couple of times recently I've needed to copy out a substring to a buffer with
limited size. Use of strncpy() or osmo_strlcpy() are nontrivial here.
I wanted to have a dedicated function.

After I wrote that function with a test, I noticed that I had already
implemented the same thing a while ago, as osmo_print_n() :P
So here is just the test.
