Bug 1454380 [wpt PR 8508] - Test that requestMediaKeySystemAccess sets label, a=testonly

Automatic update from web-platform-testsTest that requestMediaKeySystemAccess sets label (#8508)

On Edge, navigator.requestMediaKeySystemAccess ignores the value passed along to the label configuration field.  This test exposes that bug.
