    gnu: usbredir: Build without '-Werror'.
    
    Fixes build failure introduced in
    58ee8a94a90eb40496b9704d541b5dfbbf1685ba, where compilation would fail
    with:
    
      usbredirhost.c: In function ?usbredirhost_open_full?:
      usbredirhost.c:749:5: error: ?libusb_set_debug? is deprecated: Use 
libusb_set_option instead [-Werror=deprecated-declarations]
           libusb_set_debug(host->ctx, host->verbose);
           ^
      In file included from usbredirhost.h:24:0,
                   from usbredirhost.c:31:

 note: declared here
       void LIBUSB_CALL libusb_set_debug(libusb_context *ctx, int level);
                    ^
      cc1: all warnings being treated as errors
    
    * gnu/packages/spice.scm (usbredir)[arguments]: In 'autogen' phase,
    remove '-Werror' from configure.ac.
