Update r228592 for when gethostname() returns an error

If gethostname() is not successful, just skip adding the hostname to the
module hash.  And don't bother setting hostname[255] = 0, since if
gethostname() is successful, it will be null-terminated already (and if
it's not successful we don't read the string now.
