[grilo] net: detect in runtime use-thread-context property

[Victor Manuel Jaquez Leal <vjaquez src gnome org>]

commit a7f2d378afebd88877030d6bc8f1e7124dff919c

    net: detect in runtime use-thread-context property
    
    Instead of messing with autotools, it is better to know in run-time if
    the required property is available.
    
    Revert "grl-net: Use libsoup context threads for libsoup 2.39 or above"
    This reverts commit 98fb065f9d52092d2cbf29dcdc1784f9ff087e74.
