auth_krb5:  do not try to build it when com_err header is not found

The new krb5.m4 used by INN does not guarantee that com_err.h
will exist because it's no longer part of the official Kerberos API.
Therefore, add a special check to clear KRB5_AUTH, KRB5_CPPFLAGS,
KRB5_LDFLAGS, and KRB5_LIBS if neither et/com_err.h nor com_err.h
can be found and --with-krb5 is not given.

Thanks to Jesse Rehmer for the bug report.
