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/decap_sanity.c:9:
.../netinet/in.h:23:8: error: redefinition of 'struct in6_addr'
