[#25136] YSQL: Decrease number of iteration in PgLibPqTest.MasterRest…

…artReadPastGlobalLimit TSAN mode

Summary:
The test performs 10k iterations, in TSAN mode it takes 0.1s to perform single iteration in TSAN mode.
So test just times out because 15 minutes is required to complete such number of iterations.

Decreased number of iterations to 1k for sanitizers.
