binman: test: Capture output from tests with warnings

Tests are supposed to run silently and capture any output produced.

Fix testRemoveTemplate() so that the message about the missing openssl
is captured, along with the invalid-images message.

Fix testNxpImx9Image() as well, since it is expected that container.img
and bl31.bin are missing.
