[gdb/testsuite] Fix gdb.arch/arm-single-step-kernel-helper.exp
On arm-linux I run into: ... (gdb) p *kernel_user_helper_version^M Cannot access memory at address 0xffff0ffc^M (gdb) FAIL: gdb.arch/arm-single-step-kernel-helper.exp: check kernel helper version ... What the test-case is trying to do, is to access a special address in the arm linux kernel [1] using ptrace, which doesn't seem to work. This is with kernel version 6.1.55. Perhaps this used to work, but the kernel was modified to be more strict with respect to access to this special address. Fix this by making the inferior access that special address instead. Tested on arm-linux.
