Increase "rndc dnssec -status" output size

BUFSIZ (512 bytes on Windows) may not be enough to fit the status of a
DNSSEC policy and three DNSSEC keys.

Set the size of the relevant buffer to a hardcoded value of 4096 bytes,
which should be enough for most scenarios.

84 jobs for !3804 with 1988-windows-rndc-dnssec-status-bad-output-v9_16 in 21 minutes and 8 seconds (queued for 26 seconds)
