unigbrk/uc-grapheme-breaks: Fix build failure

[Bruno Haible]

This command fails:

$ ./gnulib-tool --test --with-tests --single-configure 
unigbrk/uc-grapheme-breaks
...
gllib/Makefile.am:1706: error: LIBUNISTRING_COMPILE_UNIGBRK_U32_GRAPHEME_BREAKS 
does not appear in AM_CONDITIONAL

After the type in the Makefile.am is fixed, there is another error:

../../gllib/unigbrk/uc-grapheme-breaks.c:25:20: fatal error: unistr.h: No such 
file or directory

Here's the fix:

        * lib/unigbrk/uc-grapheme-breaks.c: Don't include unistr.h.
