Update gcc version for FBGEMM install in CI (#2654)

Summary:

TorchRec CI currently is failing with issues on incompatible GLIBCXX version. The cause is that FBGEMM now requires g++ 11.1+ for building binaries that reference GLIBCXX_3.4.29 (as of pytorch/pytorch#141035)

As recommended in https://github.com/pytorch/FBGEMM/blob/main/.github/scripts/utils_build.bash and pytorch/FBGEMM#3423, install GCC using conda to control glibcxx version being used.
