[arch-general] Updated scripts for removing duplicates from /var/cache/pacman/pkg

[David C. Rankin]

Just FYI - Scripts updated to:

(1) provide a -f | --force option to the fduparch.sh (wrapper) script to 
ignore the md5sum directory check and force a scan of all package and 
duplicate directories. (by default if dir md5sums are unchanged, duplicate 
scanning is skipped)

(2) provide automatic clipping of long package names to terminal width with 
ellipse (...) indicators added to show clipping occurred. (stopped the 
kdeplasma-blah-blah... filenames from running off screen and wrapping)
