In #109133 @alyssais discovered that the drmSupport flag stopped
working. This is because Mozilla decided around Firefox 51
(mozbz#1289634) to swap the default values and our flag was asking for
the wrong thing all along.

Since this flag has now been enabled for multiple years, disabling it
would mean a regression for our users. Leaving it enabled should be
unproblematic since it only controls whether Firefox shows the EME nagbar,
that allows to enable Widevine CDM, when a site requests it. The choice is
therefore completely up to the enduser.

Disabling this nagbar is still possible at runtime by setting
browser.eme.ui.enabled to false. If Widevine CDM was inadvertently
enabled it can be disabled at media.gmp-widevinecdm.enabled.

Supersedes: #109133
