kselftest/devices/probe: Fix SyntaxWarning in regex strings for Python3

Browse source 
Insert raw strings to prevent Python3 from interpreting string literals
as Unicode strings and "\d" as invalid escaped sequence.

Fix the warnings:

tools/testing/selftests/devices/probe/test_discoverable_devices.py:48:
SyntaxWarning: invalid escape sequence '\d' usb_controller_sysfs_dir =
"usb[\d]+"

tools/testing/selftests/devices/probe/test_discoverable_devices.py: 94:
SyntaxWarning: invalid escape sequence '\d' re_usb_version =
re.compile("PRODUCT=.*/(\d)/.*")

Fixes: dacf1d7a78 ("kselftest: Add test to verify probe of devices from discoverable buses")
