examples: Fix elf/module/posix_spawn sometimes parallel build errors at link time

Browse Source 
It seems in the time window mksymtab.sh redirect to symtab.c, there is chance symtab.c
would also be built meantime. Then if built before symtab.c write done, link errors may
occur. So use rename and mv operation to reduce the possibility.
