Adjust scan string for PIE

The order of address in the first operand is different due to different
output orders of PLUS between output_addr_const and output_pic_addr_const.
This patch adjusts scan string for PIE in gcc.target/i386/pr54445-2.c.

	* gcc.target/i386/pr54445-2.c: Adjust scan string for PIE.
