Fix some paths

When the scripts were moved to /scripts I only halfway corrected the
paths to the job posting directory. Corrected now.
No, I had it right the first time.

Put the paths back. PEBCAK.
Correct the paths to the files

*sigh*

Now that the directory paths are correct the output files' paths are
not. Corrected.

My brain is having issues right relative paths this morning for some
reason. Time to make more tea.
Finally got it right

* Many tweaks to scripts/create_companies_list.pl. It actually *works*
now. I know: crazy.
* First "real" versions of the Perl_Companies.* files. They still need
deduplication.
