    selftests/bpf: Fix missing UINT_MAX definitions in benchmarks
    
    [ Upstream commit a2c155131b710959beb508ca6a54769b6b1bd488 ]
    
    Include <limits.h> in 'bench.h' to provide a UINT_MAX definition and avoid
    multiple compile errors against mips64el/musl-libc like:
    
      benchs/bench_local_storage.c: In function 'parse_arg':
      benchs/bench_local_storage.c:40:38: error: 'UINT_MAX' undeclared (first use in this function)
         40 |                 if (ret < 1 || ret > UINT_MAX) {
            |                                      ^~~~~~~~
      benchs/bench_local_storage.c:11:1: note: 'UINT_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'?
         10 | #include <test_btf.h>
        +++ |+#include <limits.h>
         11 |
    
    seen with bench_local_storage.c, bench_local_storage_rcu_tasks_trace.c, and
    bench_bpf_hashmap_lookup.c.
