contrib: update thunderbird-patch-inline

This script uses an extension to run an external editor from
thunderbird that is no-longer maintained. Replace it with a different
extension that is maintained[1]. The new extension uses a different
separator between the mail headers and message body so update the
script to accommodate that.
