cuneiform: Fix build against glibc 2.26

Since glibc 2.26 the string.h file includes <strings.h>, which in case
of cuneiform will include the strings.h found in Kern/hhh/tigerh/h,
because of the search path order.

Fortunately for us the strings.h in cuneiform are completely unused and
no files reference or include it. I even checked various references to
types within strings.h and the only occurences are in cf_strings.h,
which is also included by other files.
