Fix build on FreeBSD.
FreeBSD lacks the constant HOST_NAME_MAX, instead using sysconf(3) to find out the value of the maximum host name length at run time. Patch to use this instead of HOST_NAME_MAX. This brings with it the need to use malloc instead of using a statically sized buffer for the host name, since the size of the buffer cannot be known at run time. Errors from sysconf or malloc just means that the entire block of code is skipped over (the same way it's skipped if the call to gethostname() fails), rather than returning any kind of error to the caller or logging an error message somewhere.
