Frederic Berat 0371c23623 debug/readlink{, at}_chk.c: Harmonize declaration and definition
The declaration and definition of these routines aren't consistent.

Make the definition of __readlink_chk and __readlinkat_chk match the
declaration of the routines they fortify.  While there are no problems
today this avoids any future potential problems related to the mismatch.
