Strange parsing exeception when using in-repo `./mill` script

[Tobias Roeser]

Noticed it, while analyzing, why one of our Github Actions fail constantly.

> ./mill --import ivy:io.chris-kipp::mill-github-dependency-graph::0.2.6 resolve io.kipp.mill.github.dependency.graph.Graph/generate
[build.sc] [47/53] zincReportCachedProblems 
Parsing exception Position 1:14, found "=./mill"

It does not happen if I run it with just mill.

> mill --import ivy:io.chris-kipp::mill-github-dependency-graph::0.2.6  resolve io.kipp.mill.github.dependency.graph.Graph/generate
[1/1] resolve 
generate

It's also not happening when I use millw

> ./millw --import ivy:io.chris-kipp::mill-github-dependency-graph::0.2.6 resolve io.kipp.mill.github.dependency.graph.Graph/generate
[1/1] resolve 
generate

So, it must be something within our in-repo mill script.

There is probably some issue with the first arg detection. Maybe the --import is matched by the code that is supposed to match -i.
