619662adb6 Add readonly to SC2155 
This adds a warning for readonly masking the return value of function.
This is mentioned in the wiki
https://github.com/koalaman/shellcheck/wiki/SC2155#problematic-code-in-the-case-of-readonly
but didn't actually produce a warning.

Fixes https://github.com/koalaman/shellcheck/issues/1336
