Subject: [PATCH] sbang: Fix perl binary detection

The perl binary can also be called `perlX.Y.Z` if using a development
build or simply using the versioned binary.

We were also dropping all sbang arguments, since `exec $interpreter_v`
was only using the first element of the `interpreter_v` array.
