Revert "[macOS] Request camera permission before session init."

This reverts commit 3fea85a6f0c7beb18841b68e5bed5c8ff01a8a51.

The commit is good but to use `@available(macOS 10.14, *)` with osxcross one
needs to build `compiler-rt`, which can be done but might surprise some users
who have their custom build pipelines for 3.3.x (including the official build
system).
