maintainer-makefile: Fix false syntax-check failure when using inttostr.

[Collin Funk]

Hi,

While working on an inetutils patch I wrote something like:

   #include "inttostr.h"

   char *str = inttostr (...);

Afterwards, running 'make syntax-check' mistakenly yelled at me:

    maint.mk: the above files include inttostr.h but don't use it
    make: *** [maint.mk:694: sc_prohibit_inttostr_without_use] Error 1

That is because the regex didn't match "inttostr". I pushed the
attached patch to fix it.

Collin
