[Bashburn-info] Fix up misc/check_path.sh

[Nick W. <ni...@li...>]

I noticed this wasn't working right - I was told I had to install
missing apps even if I had them all.

Looking at this, it was sooooooo convoluted logic the way a missing app
was looked at.  Putting echoes in, I was getting 14 apps found and 25
nr_apps.

Also, I haven't a clue what this line did:

nr_apps=$(( ${#BBBURNING} + ${#BBRIPPERS} + ${#BBXCODERS} +
${#BBMISC} ))

Anyway, it is now fixed - easy to read and will always work, no matter
how many apps are added at a later date.

The function is already THERE to test if an app exists.  All we need to
do is count the MISSING ones.  If after the function,
bb_not_found_apps != 0, then we know (but don't care which, the
function deals with that) apps are missing, and thus just print the
warning.

Oh, also the reason I looked at this file was to add a 'clear' so the
display is all nice when the paths are printed to stdout.
