Check out the Poetry and Pipenv lock fixtures byte-exact on Windows

The Windows test leg's CRLF checkout (core.autocrlf) turned the LF-committed
tests/fixtures/poetry, pipenv and pipenv-shapes locks into CRLF, so the
byte-exact upstream-restore round trips (and their derived CRLF variants,
which became \r\r\n) and the Poetry VEX pin-spelling test failed on
Windows only. Mark them -text like the other captured-lock fixtures.
