examples/fstest: For SPIFFS, add garbage collection and file system integrity IOCTL calls. This was to avoid running out of FLASH space while running the fstest (ENOSPC=28). However, it does not work.. still runs out of memory.

SPIFFS garbage collection and integrity checking will be performed
after a write fails with ENOSPC.
If this option is not selected then the SPIFFS FLASH will likely
become full before you finish the test.
