cmd: ufetch: Fix type mismatch on 32-bit

On 32-bit architectures, LAST_LINE (_LAST_LINE - 1UL) is 64 bits long,
but size_t (from ARRAY_SIZE(...)) is 32 bits. This results in a warning
because the max() macro expects the same type on both sides:

cmd/ufetch.c: In function ‘do_ufetch’:
include/linux/kernel.h:179:24: warning: comparison of distinct pointer types lacks a cast [-Wcompare-distinct-pointer-types]
  179 |         (void) (&_max1 == &_max2);              \
      |                        ^~
cmd/ufetch.c:92:25: note: in expansion of macro ‘max’
   92 |         int num_lines = max(LAST_LINE + 1, ARRAY_SIZE(logo_lines));
      |                         ^~~

Fix this by casting LAST_LINE to size_t.
