test,unix: reduce stack size of watchdog threads

Browse Source 
Some 32 bits architectures, linux/mips and linux/mipsel in particular,
suffer from address space fragmentation when spawning many threads
with the default 8 MB stack size.  The watchdog threads don't need
much stack space, all they do is sleep until the monitored process
exits, so lower it to 256 kB.
