[PATCH] hda-emu: Improve directory/path handling for testsuite

[David Henningsson <david.henningsson@canonical.com>]

There were some shortcomings when running the test scripts from
a random directory. Also added functionality to test an entire
directory tree at the same time.

With this improvement we can run it over the entire alsa-info database.
The initial result is 619 of 5911 (10%) failing, mostly due to invalid verbs sent
(no input/output-amp, invalid amp index, setting *_EN without caps, etc).
