PATCH: always restore variables in multipass mode

This was found while splitting a new variable out of some uses of 
$srcdir when Emacs paren highlighting did not look right.  Sure enough, 
the per-pass variables are set unconditionally, but are only restored if 
the "Go digging for tests" branch was taken.  This patch moves that loop 
out of an "else" block and into the same "foreach" that contains the 
loop that sets per-pass variables.

ChangeLog entry:
----
	* runtest.exp: Ensure that multipass pass variables are always
	restored.  Previously, they were only restored if the "Go digging
	for tests" branch was taken near the end of runtest.exp.
