Nicolas Fella 2548455f45 Copy FindSharedMimeInfo from ECM
Instead of relying on ECM being installed.

We copy other stuff from ECM so be consistent.

# FindSharedMimeInfo
# ------------------
#
# Try to find the shared-mime-info package.
#
# This will define the following variables:
#
# ``SharedMimeInfo_FOUND``
# True if system has the shared-mime-info package
# ``UPDATE_MIME_DATABASE_EXECUTABLE``
# The update-mime-database executable
#
# and the following imported targets:
#
# ``SharedMimeInfo::UpdateMimeDatabase``
# The update-mime-database executable
#
# The follow macro is available::
#
# update_xdg_mimetypes(<path>)
#
# Updates the XDG mime database at install time (unless the ``$DESTDIR``
# environment variable is set, in which case it is up to package managers to
# perform this task).
#
# Since pre-1.0.0.
