fix: switch 8.0.1 Dockerfile from archive to git clone (#604)

OpenEMR's .gitattributes now marks tests/, phpunit*.xml, and other
dev files as export-ignore (openemr/openemr#11213). GitHub archives
respect these rules, so the 8.0.1 image was missing test files needed
by the CI test suite.

Switch to git clone --depth 1 which ignores export-ignore rules,
matching the approach used by the older production Dockerfiles.

Fixes #603
