[kernel] Avoid capturing blanket 'find -ls'

Previously, if sos was run in an environment where '/lib/modules/*' did
not exist, the kernel plugin would pass an empty extra_mod_paths list to
'find -ls', which would in turn cause sos to execute 'find -ls' on the
entire filesystem.

While this situation may seem rare, this is a possiblity whenever sos is
run in a container that does not have the proper environment variable
set that indicates to the active policy that sos is in fact in  a
container. On top of generating a sosreport with little to useful
information in this case, the generated sosreport could potentially be
very large due to the collection of a blanket 'find -ls'.

This prevents this from occuring, by not running 'find -ls' if the
extra_mod_paths list is empty.

Resolves: #1288
