examples: remove test script

In commit 2e233285 (examples: a test, for rev-list, 2013-03-20),
a script was introduced with the intention of testing our
rev-list example code. Nobody uses that script, and in fact it
doesn't even properly work due to the not-so-recent addition
out-of-source builds.

Remove the script.
