Jim Warner 39980d6e31 watch: use sysconf() for hostname length __ (catch up) ...

--------------- Original Master Branch Commit Message:
Hurd doesn't have HOST_NAME_MAX, neither does Solaris.
An early fix just checked for this value and used 64 instead.
This change uses sysconf which is the correct method, possibly until
this compiles on some mis-behaving OS which doesn't have this value.
