sandbox: Remove the flag --sandbox_block_path.

It is in the way of optimizing the performance of the sandbox, because
it requires us to create two helper files (an unreadable file and an
unreadable directory) which are bind-mounted on top of paths specified
via this flag. These two helper files were created on a tmpfs mounted by
the sandbox until now, which ensured that they were automatically
deleted on exit. However, mounting tmpfs on /dev/shm or /tmp causes
issues like #2686 or #1882.

By removing this flag, we can get rid of the two helper files, which
means we can also remove the reliance on a "sandbox temp directory"
completely in the next change.
