zdev: implement --shell command line switch

Browse Source 
Fix issue in the lszdev command where column names if using the --pairs
command line switch can contain characters that are not allowed to be
used as variable names in a shell environment.

Replace bad characters in column names by an underscore if the --shell
command line switch is specified along with the --pairs switch.

The additional --shell switch mimics what is already available in the
lsblk command and thus it shall be used along with the --pairs switch.
