Using sysconf(3) API lead to accidental introduction of variable length arrays
(VLA) in the port. Additionally gethostname(3) has been passed _SC_HOST_NAME_MAX
incorrectly as the HOST_NAME_MAX length.
Fall back to using _POSIX_HOST_NAME_MAX as the remaining code is not ready for
introducing sysconf(3) as a patch.
Bump PORTREVISION to rebuild with the new patch.
