strnlen.3: Fix a small inconsistency in the text 

Quoting Heinrich:

    The strnlen.3 manpage has the following sentence:

    "In doing this, strnlen() looks only at the first maxlen
    characters in the string pointed to by s and never beyond
    s+maxlen."

    This sentence is self-contradictory:

    The last visited character implied by "first maxlen
    characters" is s[maxlen-1].

    Given that "beyond a" does not include "a", the last visited
    character implied by "never beyond s+maxlen" is s[maxlen].

    A consistent sentence would be

    "In doing this, strnlen() looks only at the first maxlen
    characters in the string pointed to by s and never beyond
    s+maxlen-1."

    I would prefer

    "In doing this, strnlen() looks only at the first maxlen
    characters in the string pointed to by s and never beyond
    s[maxlen-1]"
