[ASan] Really fix zero_page_pc test for PowerPC
Summary:
As a follow-up to D6167, this patch fixes the test to account for
another difference between PowerPC and x86 systems.
On x86 if you branch to an invalid address, you get a SIGSEGV with PC
set to the invalid address (and si_addr in the siginfo struct also set
to the same address).
On PowerPC, you get a SIGSEGV with PC pointing at the branch
instruction, but si_addr set to the invalid address.
You can see this difference if you run the test case under gdb.
