tests/ports/esp32/check_err_str.py: Preallocate global variable.

Browse Source 
This test fails on all esp32 boards without this fix, because the
try/except that runs with the heap locked attempts to increase the size of
the globals dict when assigning to the exception variable `e`.

Fix that by preallocating the global variable `e`.
