Add "imprecise" watchpoint ptrace test
This tests for the presence of a kernel bug that meant that the kernel
would sometimes fail to report the watchpoint hit if the hardware
reported a address which did not exactly match the address range being
watched (which it is allowed to do per ARM spec if the instruction
accesses a larger block of memory than the region being watched). This
bug was fixed in linux kernel 4.9, and has been backported to older
android kernels.
