Improve new time sensitive pexpireat propagation test (#9010)
The test that was merged yesterday fails with valgrind and freebsd CI
that are too slow, and 10 seconds apparently passed between the time the
command was sent to redis and the time it was actually executed.

```
*** [err]: All TTL in commands are propagated as absolute timestamp in replication stream in tests/unit/expire.tcl
Expected 'del a' to match 'set foo1 bar PXAT *' (context: type source line 778 file /home/runner/work/redis/redis/tests/test_helper.tcl cmd {assert_match [lindex $patterns $j] [read_from_replication_stream $s]} proc ::assert_replication_stream level 1)
```
