zdev: Add function for reading text files

Browse Source 
Reduce code complexity by adding a utility function for reading text
files based on a variable path.

Note: chzdev/lszdev tools apply special path-handling via command line
option --base to allow redirecting hard-coded paths therefore libutil's
util_file functions cannot easily be used.
