MDEV-26626 fixup: SIGFPE during startup

Browse source 
srv_start(): Set srv_startup_is_before_trx_rollback_phase before
starting the buf_flush_page_cleaner() thread, so that it will not
invoke log_checkpoint() before the log file has been created.

This race condition was reproduced with https://rr-project.org.
This fixes up commit 15efb7ed48
