t8001/t8002: blame: add tests of -L line numbers less than 1

Browse source 
git-blame -L is documented as accepting 1-based line numbers. When
handed a line number less than 1, -L's behavior is undocumented and
undefined; it's also nonsensical and should be rejected but is
nevertheless accepted. Demonstrate this shortcoming.
