Subject: [PATCH 4.14 016/117] selftests: kmod: fix handling test numbers above 9

From: Eric Biggers <ebiggers@...gle.com>

[ Upstream commit 6d573a07528308eb77ec072c010819c359bebf6e ]

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.
