[PATCH bpf v1] selftests/bpf: Fix undefined UINT_MAX in veristat.c

[Tony Ambardar <tony.ambardar@xxxxxxxxx>]

Include <limits.h> in 'veristat.c' to provide a UINT_MAX definition and
avoid multiple compile errors against mips64el/musl-libc:

veristat.c: In function 'max_verifier_log_size':
veristat.c:1135:36: error: 'UINT_MAX' undeclared (first use in this function)
 1135 |         const int SMALL_LOG_SIZE = UINT_MAX >> 8;
      |                                    ^~~~~~~~
veristat.c:24:1: note: 'UINT_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'?
   23 | #include <math.h>
