[PATCH] lib: fwts_summary: fix build warning with gcc-10

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Provide enough buffer space to clean up gcc-10 build warnings such
as the following:

fwts_summary.c:178:29: error: '%5u' directive output may be
truncated writing between 5 and 10 bytes into a region of
size 6 [-Werror=format-truncation=]
  178 |   snprintf(buffer, buflen, "%5u", value);
      |                             ^~~
fwts_summary.c:178:28: note: directive argument in the range [1, 4294967295]
  178 |   snprintf(buffer, buflen, "%5u", value);
      |                            ^~~~~
