[Libosinfo] [PATCHv4 05/11] OsinfoInstallScript: Use an OsinfoInstallConfigParamList

[Christophe Fergeau]

Currently the install script config parameters are stored in a
raw GList. However, OsinfoInstallScript ends up reimplementing
part of the OsinfoList API, and the raw GList also does not make
it convenient to pass the list of config parameters around.
Replace the internal GList with an OsinfoInstallConfigParamList,
which has the side-effect of nicely simplifying the code.
