lib/shopt: tweak OMB_CASE_SENSITIVE handling in shopt (#399)

Browse Source 
The CASE_SENSITIVE setting is checked when setting case-insensitive
globbing but not matching (for features such as command / programmable
completion).  Add checks in the appropriate places, preserving the default
(insensitive) behaviour unless explicitly changed.

This will allow case-sensitivity to apply in an intuitive way, treating
paths, filename completions and command completions consistently.
