Need documented: HDCP daemon look for 'media' user

[saininav]

HDCP daemon looks for 'media' user account, which needs to be documented. In absence of this, HDCP daemon fails.

https://github.com/saininav/hdcp/blob/master/daemon/main.cpp

struct passwd *mediaId = getpwnam("media");

'media' use account is going to be removed.

When is it going to be removed? The code has had a single commit since 19.4.0 was tagged nearly two years ago..
