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.
