fix snprintf warnings from gcc 8

In recent versions of gcc, there are a few places where gcc warns:
iio_info.c: In function ‘main’:
iio_info.c:333:41: warning: ‘%u’ directive output may be truncated writing between 1 and 10 bytes into a region of size 7 [-Wformat-truncation=]
      snprintf(repeat, sizeof(repeat), "X%u",
                                         ^~
This fixes the warn by increasing the size of the buffer to 12 from 8.
No functional differences.
