Subject: [PATCH 2/2] arpd.c: Use names for struct msghdr initialisation

Fixes the following compiler error which is due to padding elements
being present in musl (1.2.5), thankfully the struct element names
are part of POSIX.

arpd.c:442:3: error: incompatible pointer to integer conversion initializing 'int' with an expression of type 'void *' [-Wint-conversion]
  442 |                 NULL,   0,
      |                 ^~~~
