checkpatch: describe --min-conf-desc-length

Neither the warning nor the help message gives any hint on the unit for
length: Could be meters, inches, bytes, characters or ...  lines.

Extend the output of `--help` to name the unit "lines" and the default:
-  --min-conf-desc-length=n   set the min description length, if shorter, warn
+  --min-conf-desc-length=n   set the minimum description length for config symbols
+                             in lines, if shorter, warn (default 4)

Include the minimum number of lines as other error messages already do:
- WARNING: please write a help paragraph that fully describes the config symbol
+ WARNING: please write a help paragraph that fully describes the config symbol with at least 4 lines
