This commit increases server start timeout from 60 to 90 seconds in order to avoid system test failures on some platforms due to inability to initialise TLS contexts in time.
(cherry picked from commit 705f0d1e)
v9_18 and v9_18_sub branches are the only maintained branches where system:gcc:bullseye:amd64cross32 fails to start the ns1 server. It failed to start 12 times in the last two months.
Backport of MR !6356 (merged)
Closes #3269 (closed)
