autopkgtest: Fix test failure when built-in drivers request firmware

Browse Source 
On Debian armhf, the imx_sdma driver is currently built-in.  It
requests firmware and has the corresponding module metadata, and in
tests we currently generate a warning that this is missing.  Any
output to stderr results in a test failure by default.  It is possible
to override that, but I think we do generally want this behaviour.

imx_sdma could be built as a module (as it is on arm64), and it might
also make sense to remove the firmware warnings, but those will take
some time to do.  As a quick fix to let initramfs-tools to go into
testing, work around this by creating dummy files for any firmware
listed in built-in module metadata.

This fixes the other half of #1078168.
