[PATCH] t6030 (bisect): work around Mac OS X "ls"

t6030-bisect-porcelain.sh relies on "ls" exiting with nonzero
status when asked to list nonexistent files.  Unfortunately,
/bin/ls on Mac OS X 10.3 exits with exit code 0.  So use "echo
<shell glob pattern>" and grep instead.

	With this change, all the non-git-svn tests pass on my machine.
	I think the fix is portable but I do not have the experience to
	be sure.  So I would be happier if someone looks it over.
