t6130/t9350: prepare for stringent Win32 path validation

On Windows, file names cannot contain asterisks nor newline characters.
In an upcoming commit, we will make this limitation explicit,
disallowing even the creation of commits that introduce such file names.

However, in the test scripts touched by this patch, we _know_ that those
paths won't be checked out, so we _want_ to allow such file names.

Happily, the stringent path validation will be guarded via the
`core.protectNTFS` flag, so all we need to do is to force that flag off
temporarily.
