MDEV-7273 - 10.1 fails to start up during tc_log initializations on PPC64
log-tc-size is 24K by default. Page size is 64K on PPC64. But log-tc-
size
must be at least 3 x page size. This is enforced by TC_LOG_MMAP::open()
with a comment: to guarantee non-empty pool.
This all makes server not startable in default configuration on PPC64.
Autosize log-tc-size, so that it's min value= page size * 3, default
value= page size * 6, block size= page size.
