The Net::DNS Perl module needs the Digest::HMAC module to support TSIG.
However, since the latter is not a hard requirement for the former, some
packagers do not make Net::DNS depend on Digest::HMAC. If Net::DNS is
installed on a host but Digest::HMAC is not, the "xfer" system test
breaks in a very hard-to-debug way (ans5 returns TSIG RRs with empty
RDATA, which prevents TSIG-signed SOA queries and transfers from
working). Prevent this from happening by making the "xfer" system test
explicitly require Digest::HMAC apart from Net::DNS.
Every prereq.sh script must include bin/tests/system/conf.sh, otherwise
if some prerequisite is not met, errors about echo_i not being found
will be printed instead of actual error messages.
