selftests: kmod: fix handling test numbers above 9

[ Upstream commit 69d70a59fbd3ae503676b57a9e20762d640f29f1 ]

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.
