Bug 1443925 - Part 1: Support running GetBlobURLPrincipal off-main-thread, r=asuth

Browse Source 
This method isn't actually safe to run off-main-thread yet, as nsIPrincipal
manipulation isn't being made threadsafe until a later part, however it can be
called off-main-thread when creating a new content principal with a Blob URL
spec.
