[PATCH] testsuite: Fix vect_long_mult on Power [PR109705]

["Kewen.Lin" <linkw@linux.ibm.com>]

Hi,

As pointed out by the discussion in PR109705, the current
vect_long_mult effective target check on Power is broken.
This patch is to fix it accordingly.

With additional change by adding a guard vect_long_mult
in gcc.dg/vect/pr25413a.c , it's tested well on Power{8,9}
LE & BE (also on Power10 LE as before).

I'm going to push this soon.

BR,
Kewen
