Poll the flash status instead of just reading the flash status once. Add
support for controlling the number of SDO retries and the SDO timeouts.
These changes allows for greater control of the CANopen program
download, which is especially useful on noisy or congested CAN networks
and on devices with slower flash access.

Copy a fix from test_nrfjprog.py to the other runner test suites. The
current code will enter an infinite recursion if you hit the path
where os.path.isfile is called, since it's been patched to
os_path_isfile_patch in the calling context. The fix is to cache the
'real' version in the parent scope and call it directly as a fallback.
