test_select_reuseport_kern.c is currently including <stdlib.h>, but it
does not use any definition from there.

Remove stdlib.h inclusion from test_select_reuseport_kern.c

I stumbled upon this specific header include while trying to build selftests on
the current bpf-next_base branch, which ended with this error:

[...]
  CLNG-BPF [test_progs-cpuv4] test_select_reuseport_kern.bpf.o
In file included from progs/test_select_reuseport_kern.c:4:
/usr/include/bits/floatn.h:83:52: error: unsupported machine mode
'__TC__'
   83 | typedef _Complex float __cfloat128 __attribute__ ((__mode__
(__TC__)));
      |                                                    ^
/usr/include/bits/floatn.h:97:9: error: __float128 is not supported on
this target
   97 | typedef __float128 _Float128;

The exact error (unknown TC mode) is likely rather due to some issues in
my local build, in which I am actually cross-compiling selftests  (for
ARM64 from a x86_64 host, but not through vmtests.sh), and I still have
to sort out some other issues. But I guess it is not really right anyway
to include stdlib.h from an ebpf program, especially if it is not used,
so I am still proposing this small change.
