[context] wildcard support in dnf_context_repo_set_data (RhBug:1781420)

Adds support for wildcard pattern in repo_id to these functions:
gboolean dnf_context_repo_enable(DnfContext *context,
    const gchar *repo_id, GError **error);
gboolean dnf_context_repo_disable(DnfContext *context,
    const gchar *repo_id, GError **error);

For example, it is used by microdnf for enable and disable repositories
(arguments "--enablerepo=" and "--disablerepo=").
