Find more tempdirs
* Find G303 in string concatenations, with os.TempDir, and in path.Join args

* Find G303 with /usr/tmp, too

/usr/tmp is commonly found e.g. on Solaris.

feat: add os.ReadFile to G304 (#706)
In Go 1.16 or higher, the `io/ioutil` has been deprecated and the
`ioutil.ReadFile` function now calls `os.ReadFile`.

Improve the G307 rule
* Add G307 sample code.
The sample should reflect a defered close that leads to data loss.
Due to IDE auto-complete people tend at least log errors, but not
really care about handling.

* Add more G307 sample code. Propose a way to implement

* Remove unused code. Add example that should not return an error but does

* Remove test for synced closed file for now.
Will add this later

709ed1ba65 Change rule G204 to be less restrictive (#339)
Currently, rule G204 warns you about every single use of the
functions syscall.Exec, os.exec.CommandContext and os.Exec.Command.
This can create false positives and it's not accurate because you can
use those functions with perfectly secure arguments like hardcoded
strings for example.

With this change, G204 will warn you in 3 cases when passing arguments
to a function which starts a new process the arguments:
1) are variables initialized by calling another function
2) are functions
3) are command-line arguments or environmental variables
