Use TensorPipe libuv in Gloo (#77312)
Otherwise, its possible to build TensorPipe with one version of libuv
and gloo with another.
Also, delete strange `GLOO_INSTALL` logic, as none of the install artifacts are really packaged as part of PyTorch (and it were probably used by Caffe2 builds)
This helps solve problem for compiling PyTorch for M1, where `libuv` is not available in conda
