Subject: [PATCH] testutil/pkgdata: Add MakeTestDeb()

Add MakeTestDeb() function to testutil/pkgdata. This function is just
like MakeDeb() except that it doesn't return an error. Instead, it
panics on errors.

This is useful in tests where package data is created in top-level test
case structures where we don't need to handle the error, e.g.:

	var testCases = []TestCase{{
		pkg: MakeTestDeb([]TarEntry{
			...
		}),
	}, {
		...
	}}
