8bb5e01401 Allow env to have flags and variables in shebang 
The `env` command has a `-S,--split-string` option which enables
having arguments for the command in a shebang.

Also, one could use variable assignments for the command since
`env` treats only the first word without a `=` character as the
command to run.

Fixes #2143.

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.
