PATCH v2 1/1 lib/igt_eld: introduce eld_is_supported

We've seen cases in which /proc/asound doesn't exist (e.g. with the new SOF framework). We've also seen cases in which no soundcard is exposed by ALSA (see bugzilla link). Last, some audio drivers din't support ELDs (non-Intel drivers). In all of these cases, skipping the tests depending on ELD support makes more sense and makes it clearer what happens.

v2: also check that the driver supports ELDs entries in procfs
