[ Upstream commit 5f9dd2e896a91bfca90f8463eb6808c03d535d8a ]

This patch fixes inconsistencies in the parsing rules of the levels 1 and 2 of the kselftest_deps.sh. It was added the levels 4 and 5 to account for a few edge cases that are present in some tests, also some minor identation styling have been fixed (s/ /\t/g).
