GCC 7 now warns about potential truncation in printf statements, causing
the build to fail (due to -Werror). Expand the size of our temporary
buffer to make GCC happy.
element_bitmap.c: In function ‘parse_bitmap_element.isra.0’:
element_bitmap.c:96:59: error: ‘%zu’ directive output may be truncated writing between 1 and 20 bytes into a region of size 3 [-Werror=format-truncation=]
snprintf(i_name + 3, sizeof(i_name) - 3, "%zu", i);
^~~
element_bitmap.c:96:58: note: directive argument in the range [0, 18446744073709551614]
snprintf(i_name + 3, sizeof(i_name) - 3, "%zu", i);
^~~~~
element_bitmap.c:96:17: note: ‘snprintf’ output between 2 and 21 bytes into a destination of size 3
snprintf(i_name + 3, sizeof(i_name) - 3, "%zu", i);
