Subject: [PATCH] download_and_compile.sh: more reliable test in _gitDownload()

Before this change, using OSG with download_and_compile.sh several times
in the same directory would fail because the upstream repo for OSG has
none of README, README.txt and README.rst at top-level (it has a
README.md). Testing for the .git dir is definitely more reliable.
