Add strerrordesc_np() and strerrorname_np().
strerrordesc_np() isn't very useful (being just another name for
strerror()), but strerrorname_np() lets you get "ENOSYS" for ENOSYS,
which will make some of our test assertion messages clearer when we
switch over from strerror().
This also adds `%#m` formatting to all the relevant functions.
Test: treehugger
