pgsql: Use --no-loop for new calls of pg_receivewal --endpos in TAP tes

Use --no-loop for new calls of pg_receivewal --endpos in TAP tests

Those tests are not designed to fail, but if they do, like on some cases
for Windows because of ZLIB (?), they could remain stuck. Using
--no-loop makes the test fail immediately. The oldest test with
--endpos already did that.

Those tests have been added in ffc9dda.
