Modified Files:
        src/tests/lib/libc/sys: t_ptrace_wait.c

Log Message:
Add new ATF tests in t_ptrace_wait*

New tests:
 - access_regs_set_unaligned_pc_0x1
 - access_regs_set_unaligned_pc_0x3
 - access_regs_set_unaligned_pc_0x7

The purpose of these tests is check whether unaligned PC can panic the
kernel. If there is a panic it is fine to return EINVAL on PT_SETREGS.
New tests check respectively pc |= 0x1, pc |= 0x3 and pc |= 0x7.

Inspired by https://marc.info/?l=openbsd-bugs&m=107558043319084&w=2

While there fix access_regs6 to really test PT_SETREGS.
