[PATCH 05/19] contrib/examples/git-repack.sh: convert test -a/-o to && and ||

The interaction with unary operators and operator precedence
for && and || are better known than -a and -o, and for that
reason we prefer them. Replace all existing instances
of -a and -o to save readers from the burden of thinking
about such things.
