Fix potential rare failure in the kerberos TAP tests
Instead of writing a query to psql's stdin, which can cause a failure where psql exits before writing, reporting a write failure with a broken pipe, this changes the logic to use -c. This was not seen in the buildfarm as no animals with a sensitive environment are running the kerberos tests, but let's be safe. HEAD is able to handle the situation as of6d41dd0
for all the test suites doing connection checks.f44b9b6
has fixed the same problem for the LDAP tests. Discussion: https://postgr.es/m/YGu7ceWAiSNQDgH5@paquier.xyz Backpatch-through: 11
