doh_test exceeds run time limit on FreeBSD 14

On main, the doh unit test fails every other day, e.g., in the doh_recv_send_POST_TLS_quota check on FreeBSD 14.1 but apparently not on FreeBSD 13.3.

This partifular failing job is from pre-release testing, so in theory, it might be related to the isc-private/bind9!732 DoH change.
