ppc64/crtools.c: use pr_perror()

Browse Source 
In places where we have errno value set, such as after calling ptrace(),
it makes sense to use pr_perror as it appends the errno string. This
also fixes missing '\n' at the end (as pr_perror() adds it).

In places where we keep using pr_err(), don't forget to have '\n'.
