[PATCH bpf-next v1 18/19] selftests/bpf: Fix errors compiling crypto_sanity.c with musl libc

[Tony Ambardar <tony.ambardar@xxxxxxxxx>]

Remove a redundant include of '<linux/in6.h>', whose needed definitions are
already provided by 'test_progs.h'. This avoids errors seen compiling for
mips64el/musl-libc:

  In file included from .../arpa/inet.h:9,
                   from ./test_progs.h:17,
                   from prog_tests/crypto_sanity.c:10:
  .../netinet/in.h:23:8: error: redefinition of 'struct in6_addr'
     23 | struct in6_addr {
        |        ^~~~~~~~
  In file included from crypto_sanity.c:7:
  .../linux/in6.h:33:8: note: originally defined here

  .../netinet/in.h:34:8: error: redefinition of 'struct sockaddr_in6'
     34 | struct sockaddr_in6 {

  .../linux/in6.h:60:8: note: originally defined here
     60 | struct ipv6_mreq {
        |        ^~~~~~~~~
