fix version requirements of service.component import
The version of the service component package for OSGi Release 4 is using
the version 1.2.
The JavaDoc API states, that consumer of the API should use
version="[1.2,2.0)" for the version of the import.
I cannot find an implementation of the fixed version 1.2.2, perhaps this
is only supported by equinox.
