Fix term.el handling of ^Z-sequences spanning chunks

Bash will after each command send ?\032 and the current directory "/tmp"
to inform term.el.  Bash output is buffered in 4096 bytes chunks.  If a
command outputs roughly 4096 bytes then the end of the first chunk will
be "/tm" (Bug#13350).

* lisp/term.el (term-emulate-terminal): Change the regexp to find the
end of the ?\032 sequence to use \n instead of $, the latter can match
end of string as well.
