Matrix Portal M4 Dection Broken on 10.x

[FoamyGuy]

Under 10.x the Matrix Portal M4 device raises this error:

Traceback (most recent call last):
  File "code.py", line 1, in <module>
  File "adafruit_matrixportal/matrixportal.py", line 36, in <module>
  File "adafruit_matrixportal/network.py", line 38, in <module>
  File "adafruit_portalbase/wifi_esp32s2.py", line 25, in <module>
ImportError: no module named 'ssl'

because it gets misidentified as not a samd51. The value of os.uname().sysname appears to have changed leading to the logic here

Adafruit_CircuitPython_MatrixPortal/adafruit_matrixportal/network.py

Lines 35 to 38 in f6678a7

	if os.uname().sysname == "samd51":
	from adafruit_portalbase.wifi_coprocessor import WiFi
	else:
	from adafruit_portalbase.wifi_esp32s2 import WiFi

being broken for that case.

This must be due to adafruit/circuitpython#10145.
