Documentation: Add instruction about entitlements in BuildInstructions

The QEMU's `--accel hvf` command was recently enabled in the `run.sh`
script, but it sadly doesn't work on macOS Big Sur: you need to first
sign your code by adding an `entitlements.xml` file and running a
simple command.

- bash is needed because the default version installed on macOS doesn't support globstar
- If you install some commercial EXT2 macOS fs handler instead of osxfuse and fuse-ext2, you will need to `brew install e2fsprogs` to obtain `mke2fs` anyway.
- As of 2020-08-06, you might need to tell the build system about your newer host compiler. Once you've built the toolchain, navigate to `Build/`, `rm -rf *`, then run `cmake .. -G Ninja -DCMAKE_C_COMPILER=gcc-10 -DCMAKE_CXX_COMPILER=g++-10`, then continue with `ninja install` as usual.
- If you are on macOS Big Sur, you will need to manually enable QEMU's acceleration before running Serenity, by creating a new file called `entitlements.xml` in the `Build/` folder, with the content below, and then run the command: `codesign -s - --entitlements entitlements.xml --force /usr/local/bin/qemu-system-x86_64`; otherwise the run command will fail.
