t: fix quotes tests for --pathspec-from-file

While working on the next patch, I also noticed that quotes testing via
`"\"file\\101.t\""` was somewhat incorrect: I escaped `\` one time while
I had to escape it two times! Tests still worked due to `"` being
preserved which in turn prevented pathspec from matching files.

Fix this by using here-doc instead.
