integration tests: images_test: images with multiple tags: is a NOP

[edsantiago]

Discovered during #8165, filing in case that doesn't merge.

The following lines are NOPs:

podman/test/e2e/images_test.go

Lines 83 to 89 in 7149a7c

	session.LineInOutputContainsTag("docker.io/library/alpine", "latest")
	session.LineInOutputContainsTag("docker.io/library/busybox", "glibc")
	session.LineInOutputContainsTag("foo", "a")
	session.LineInOutputContainsTag("foo", "b")
	session.LineInOutputContainsTag("foo", "c")
	session.LineInOutputContainsTag("bar", "a")
	session.LineInOutputContainsTag("bar", "b")

Adding Expect(...).To(BeTrue()) leads to a new failure: LineInOutputContainsTag() is itself broken, its map implementation is onedimensional and only tracks one tag: so in a case like the above, with foo:a, foo:b, and foo:c, only one of a/b/c will be preserved and the rest of the tests will (falsely) fail. I wrote one possible fix for it but there is almost certainly a better way to do it. I am filing this in hopes that someone can quickly dash off a cleaner more idiomatic fix. (And, again, so the issue doesn't get lost if we find a better alternative to #8165).

And hey, as long as someone's on this, could you also fix the misspelled LineInOuputStartsWith()?

A friendly reminder that this issue had no activity for 30 days.
