Add getcwd() for getting the current working directory. The behaviour matches what musl is doing except for one important difference: If the passed buf is NULL musl (and glibc) uses a big buffer on the stack and that is then strdup()'d and returned. According to the man page for getcwd() this is a glibc extension and I don't think we need it in nolibc.
