selftests/nolibc: Add test for getcwd() and readlink()

Browse source

Add a test that uses both getcwd() and readlink() so that both
are exercised.

First the happy path is tested by fetching what should be the
same string via getcwd() and readlink() and checking they match.

Then a few different combinations of bad parameters are passed to
getcwd() to make sure it returns NULL and sets errno in those
cases.
