[glibmm] Wrap g_variant_type_peek_string() by hand.

[Krzesimir Nowak <krnowak src gnome org>]

commit a38c7969eea2fb6364df1325f3ea719fae903960
Author: Krzesimir Nowak <qdlacz gmail com>
Date:   Sun Jul 22 11:59:26 2012 +0200

    Wrap g_variant_type_peek_string() by hand.
    
    * glib/src/gvarianttype.hg:
    * glib/src/gvarianttype.ccg: The wrapped function does not return
    a C string (it is not NULL terminated), so std::string(str, size)
    constructor needs to be used. I wonder how glibmm_variant test
    passed through all distchecks so far...
