This reverts commit 48f468ea7136d27bee8c598eb58c0390be7f9ca8.

Different versions of man2html generated slightly different output. This change
supports both known varieties of output.

I've found a minor problem in the script that converts man pages into
html. The current script produces two incorrect links on every html man
page. Patch from Rod Schultz, Bull.

Modify the man2html calling sequence for a clean build of SLURM from the
source directory. The old code would copy the header.txt and footer.txt
files from "srcdir" to "." and generate an error if they were the same
files. The new code just passes the pathnames of the files into the
man2html python script
