arm64: expand CFI shadow to cover 48-bit virtual addresses
Starting from Linux 4.7, arm64's defconfig enables 48-bit VAs, see:
https://git.kernel.org/torvalds/c/211102d8
On arm64, the CFI shadow configuration currently assumes that VAs
are 39-bit long, and as expected this results in a segfault on a
(defconfig) 4.7+ kernel, when linking a CFI-enabled library.
Consequently, this change increases the max target address to
account for the new max VA size.
