MDL-40002 Files: ETag value must be a quoted-string.

Browse Source 
ETag value must be double quoted, http://tools.ietf.org/html/rfc2616#section-3.11.
More details about potential impacts in MDL-39832: shortly, at least when using
HTTP Partial GET Requests (HTTP Status: 206) plus X-Sendfile HTTP Header.
In this commit, the impact is to be RFC2616 compliant when using the ETag Header.
