Reduce hardcoded paths in Evergreen code

[Dan Scott]

* Evergreen current master
* OpenSRF current master

There are still some paths that are hardcoded into scripts and libraries in Evergreen. This means that a number of additional steps are required if a user simply wants to go with "./configure; make; make install" as with most other software. If we move to that prefix-free approach in the future, then that will also simplify our documentation.

In any case, in the grammatically-challenged branch user/dbs/less_hardcoded_paths at http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/dbs/less_hardcoded_paths I have pushed a change that adds a variable for OSRFTranslatorConfig to the eg_vhost.conf sample, as well as fixes for a few scripts that currently have hardcoded paths.

Hmm, when I tried to run this just now, on the make install step, it died out with...

/usr/bin/install: will not overwrite just-created `/openils/bin/action_trigger_runner.pl' with `./support-scripts/action_trigger_runner.pl'
/usr/bin/install: will not overwrite just-created `/openils/bin/offline-blocked-list.pl' with `./support-scripts/offline-blocked-list.pl'

Will take a closer look later this upcoming week.

Rebased on current master and added a commit that prevents the makefile from trying to install the generated files twice. (Feel free to squash them down, I just wanted to show the change.)

Tested on both Fedora 20 and Ubuntu 12.04 with and without --prefix in the ./configure step... and works.

Works for me too on Ubuntu. Squashed commit as requested and pushed out to master.

Thanks Dan!
