[DOC] shell startup files, clarifications and fixes.
When Bash is started non-interactively, it runs the script pointed by
the BASH_ENV environment variable, not .bashrc. While at it, mention
Z shell in the warning too, and mention non-interactive mode
explicitly.

* gdb.texinfo (Starting) <set/show startup-with-shell>: Mention
non-interactive mode.
(Environment) <shell startup files warning>: Mention
non-interactive mode. Mention .zshenv for Z shell, and talk about
BASH_ENV instead of .bashrc for BASH.
