common: Fix 'unchecked return code' warnings
Several tools are simply not checking return code of functions marked
with 'warn_unused_result'.
Provide wrappers for the read/write functions to avoid patching old
code and providing proper error handling.
Fix the remaining ones (calls to fgets() and system()).
