lib.cli-std: fix two shell errors when AUTOMAKE is false

Browse Source 
If `AUTOMAKE` is set to `no` in the config file, it is normalized to the
empty string.

This leads to two errors if `find` is provided by Busybox.

There is a conditional where `$AUTOMAKE` is not quoted when compared to
`recursive` leading to the following error:

  /usr/share/shorewall/lib.cli-std: line 398: [: =: unary operator expected

In contrast to the non-Busybox case, we don't check for an empty
`$AUTOMAKE` before passing it as an argument to `-maxdepth`, leading to:

  /usr/bin/find: Expected a positive decimal integer argument to -maxdepth, but got -type

Refactor the conditionals to eliminate code duplication and fix these two
bugs.
