Subject: [PATCH] Use parse_headers for media endpoint uploads

micropub_media_post_for_user makes a case-sensitive search for the
Location header, which fails if the location header is all lowercase.

This change uses the `headers` fields, introduced in
2b98a4548e82f1133bf62918b0106ab99a21fa29a, to find the Location header,
regardless of case.
