[libgweather] Use locale insensitive g_ascii_dtostr() when building URI

[Giovanni Campagna <gcampagna src gnome org>]

commit 2e34b2a04d1123d44d606f5d58b56372972aee59

    Use locale insensitive g_ascii_dtostr() when building URI
    
    g_strdup_printf() depends on locale for %f, so using it results
    in URIs that fail because coordinates have commas instead of
    periods.
