dig lookup: fix DNSKEY's algorithm handling

[felixfontein]

SUMMARY

With dnspython 2.0.0+, algorithm of DNSKEY rdata is an enum type and no longer an int. Explicitly converting it to int makes sure that it is an integer.

Try ansible localhost -m debug -a 'msg={{ q("dig", "com", qtype="DNSKEY", flat=0) }}' with and without this PR, then you get

(I also updated the RRSIG field name list, while being at it.)
