[igt-dev] [PATCH] tests/kms_content_protection: Skip on hdcp_sink_capability is not found.

[Mark Yacoub]

From: Mark Yacoub <markyacoub at google.com>

[Why]
In some configurations such as kernel 5.4 on Zork with no DP connected,
debugfs will not contain hdcp_sink_capability file.

[How]
Check for hdcp_sink_capability but skip the test if file is not found.

Tested on ChromeOS Zork Kernel 5.4
