Fix sourcing prologue.inc if parent directory contains spaces

Most `tests/regression/apparmor/*.sh` scripts contain

    . $bin/prologue.inc

This will explode if one of the parent directories contains a space.

Minimized reproducer:

```
pwd=`dirname $0`
pwd=`cd $pwd ; /bin/pwd`
bin=$pwd
echo "pwd: $bin"
. $bin/prologue.inc
pwd: /tmp/foo bar
./test.sh: line 9: /tmp/foo: No such file or directory
```

Notice that test.sh tries to source `/tmp/foo` instead of `/tmp/foo bar/prologue.inc`.

The fix - as done in this commit - is to quote the prologue.inc path:

    . "$bin/prologue.inc"
