arm: fix thinko in arm_bfi_1_p() [PR105974]

I clearly wasn't thinking straight when I wrote the arm_bfi_1_p
function and used XUINT rather than UINTVAL when extracting CONST_INT
values.  It seemed to work in testing, but was incorrect and failed
RTL checking.

Fixed thusly:

gcc/ChangeLog:

	PR target/105974
	* config/arm/arm.cc (arm_bfi_1_p): Use UINTVAL instead of XUINT.
