    Fix signedness warnings in gio/ghttpproxy.c:g_http_proxy_connect()
    
    gio/ghttpproxy.c: In function ‘g_http_proxy_connect’:
    gio/ghttpproxy.c:245:17: error: comparison of integer expressions of different signedness: ‘gsize’ {aka 
‘long unsigned int’} and ‘int’
      245 |       if (nread == -1)
          |                 ^~
    gio/ghttpproxy.c:253:22: error: comparison of integer expressions of different signedness: ‘gssize’ {aka 
‘long int’} and ‘gsize’ {aka ‘long unsigned int’}
      253 |       if (bytes_read == buffer_length)
          |                      ^~
