docs: avoid use of $tmp outside of config.status use

* doc/autoconf.texi (Polymorphic Variables, Shell Substitutions):
Use $var or $t instead.
(Limitations of Usual Tools): Use $dir instead.
(Initialization Macros) <AS_TMPDIR>: Make good on the NEWS
regarding AS_TMPDIR being documented as consuming $tmp.
Suggested by Ralf Wildenhues.
