Subject: [PATCH v3 4/5] selftests: kmod: fix handling test numbers above 9

From: Eric Biggers <ebiggers@google.com>

get_test_count() and get_test_enabled() were broken for test numbers
above 9 due to awk interpreting a field specification like '$0010' as
octal rather than decimal.  Fix it by stripping the leading zeroes.
