[Qemu-devel] [PATCH v2 1/33] tests: acpi: report names of expected files in verbose mode

[Igor Mammedov <imammedo@redhat.com>]

print expected file name if it doesn't exists if
verbose mode is enabled*. It helps to avoid running
bios-tables-test under debugger to figure out missing
file name.

*)
verbose mode is enabled if "V" env. variable is set
