[obvious][arm testsuite] Fixup expected location in require-pic-register-loc.c

After r254010 we now add -gcolumn-info by default, that means the tests
in gcc.target/arm/require-pic-register-loc.c need adjusting to not expect
to see column zero.

	* gcc.target/arm/require-pic-register-loc.c: Use wider regex for
	column information.
