WebApps: Register MIME types when web app installed on Linux.
In Linux, an association between an app and a particular file is made
on the basis of the file's MIME type. Where an app supports handling
MIME types that aren't known to the OS, those types must be registered
calling `xdg-mime` [1] on an XML file containing a mapping of MIME types
to file extensions per the freedesktop.org Shared MIME-info Database
specification [2]. This CL implements methods for generating a compliant
XML file from a set of file handlers, writing it to a temp file, and
calling `xdg-mime` on that file to register the new MIME types. These
are invoked as part of the web app install process on Linux.
