Fix gtk+2.0-maemo alternate subpackages (#1299)

Specifying alternate subpackages in the provides variable of the main
package means that the main package itself is providing an alternate for
the subpackages (e.g. gtk+2.0-maemo provides an alternate gtk+2.0-dev).
The provides variable must be set for each subpackage. Fixes #1284.
