Add shebangs to each shell script

Since the shell scripts are being copied over to the remote filesystem during the build, some enviroment variables don't show up, and cause a lot of build failures. If we want to have shebangs in each shell script, then we'll need to determine an appropriate one for each, and make sure the correct environment variables come along with it.

I got curious and played around with this a little bit. It might be that we want #!/bin/bash instead of #!/bin/sh.

When I ran shellcheck on bootstrap.sh with #!/bin/sh, it reminded me that, for example:

In bootstrap.sh line 65:
debconf-set-selections <<< 'mysql-server mysql-server/root_password password islandora'
                           ^-- SC2039: In POSIX sh, here-strings are not supported.

If you want to take it on, I'm more than happy to reopen the issue.

Looks like it should be #!/bin/bash, and it seems to be working. I'll commit in push if this build is successful.
