Compiling git has a wrong symbol that leads into invalid command

The use of the branch 11-7-stable meant release managers would have to
update this file every month, which is tedious and easy to overlook. To
work around this, we simply use a placeholder and make it clear that the

Because the one we were using aren't compatible with
Ruby 2.5.3, and it'll be troublesome to switch Ruby.
Upgrading google-protobuf will be much easier.

All of them will need to be updated for Ruby 2.5.3

"/home/git/repositories" in arguments causes Gitaly installation to fail

Fixes that make this work:

* A change in Ruby (https://github.com/ruby/ruby/commit/ce635262f53b760284d56bb1027baebaaec175d1)
requires passing in the exact required length for OpenSSL keys and IVs.

* Ensure the secrets.yml is generated before any prepended modules are
loaded. This is done by renaming the `secret_token.rb` initializer to
`01_secret_token.rb`, which is a bit ugly but involves the least impact on
other files.
