Fix type of various sessionVariables options
Unfortunately, using `attrsOf` is not possible since it results in too
eager evaluation. In particular, the

    home.sessionVariables = {
      FOO = "Hello";
      BAR = "${config.home.sessionVariables.FOO} World!";
    };

example will cause an infinite recursion.

This commit restores the option type of

- `home.sessionVariables`,
- `pam.sessionVariables`,
- `programs.bash.sessionVariables`, and
- `programs.zsh.sessionVariables`

to `attrs`. It also adds test cases for the above options to avoid
regressions.

Fixes #659
