Arm: Skip new binary decode tests on pe targets

The two new test I added require the use of the ".inst" directive which the PE
targets don't support.  Because of that I excluded *-unknown-pe but the mask needs
to be wider.  I am now excluding *-*-pe.

gas/ChangeLog:

	* testsuite/gas/arm/undefined-insn-arm.d: Widen pe skip.
	* testsuite/gas/arm/undefined-insn-thumb.d: Likewise.
