Willem de Bruijn aea066ac9e selftests/net: fix a char signedness issue
[ Upstream commit 7b29828c5a ]

Signedness of char is signed on x86_64, but unsigned on arm64.

Fix the warning building cmsg_sender.c on signed platforms or
forced with -fsigned-char:

    msg_sender.c:455:12:
    error: implicit conversion from 'int' to 'char'
    changes value from 128 to -128
    [-Werror,-Wconstant-conversion]
        buf[0] = ICMPV6_ECHO_REQUEST;

constant ICMPV6_ECHO_REQUEST is 128.
