Remove support for GCC 4.7.

This reverts https://boringssl-review.googlesource.com/24924. As noted
there, GCC 4.7 support ends 2018-03-23, which has passed. GCC 4.8.0 was
released 2013-03-22, so we are now past the five year mark, matching
Abseil's guidelines.

Abseil also now explicitly lists supported compilers and explicitly
requires GCC 4.8+. https://abseil.io/docs/cpp/platforms/platforms

gRPC also now requires 4.8 per
https://github.com/grpc/grpc/issues/10036#issuecomment-290248204

Update-Note: On the off chance someone was using GCC 4.7, which only
started working in January, that'll no longer work.
