[testsuite, obvious] Remove explicit "dg-do run" from more gcc.dg/vect tests

[Sandra Loosemore <sandra at codesourcery dot com>]

This patch is a followup to PR testsuite/83889, in which it was noted that

"The failures in this PR were from forcing { dg-do run } even when
vect.exp chooses options that are incompatible with the runtime.
The default vect.exp behaviour is to execute when possible, so there's
no need for a dg-do at all."

Since the original patch for this PR was committed, a bunch of new 
testcases have been added that also incorrectly specify "dg-do run", 
leading to bogus execution failures (in the case I tripped over, trying 
to run code built for ARM Neon on a target that doesn't support those 
instructions).  I've applied the same trivial fix as in the original 
patch.  I thought this was obvious enough that I went ahead and 
committed it.
