Re: install_initd test scripts written

I'm adding three tests. I'm renumbering the
existing set of tests. The Asserts doc will need updating.

Reference 20.3-1 (A)
The implementation provides an exec-able version of the install_initd
utility in the /usr/lib/lsb/ directory.

Reference 20.3-2 (A)
The implementation provides an exec-able version of the remove_initd
utility in the /usr/lib/lsb/ directory.


Reference 20.3-3(A), The /etc/init.d directory exists

I also renumbered tp6 to be test 4.

Reference 20.4-4(A), Testing for the existance of /lib/lsb/init-functions
Spec reference: 20.2. Init Script Actions

This way we have four mandatory tests prior to other tests.
