valgrind: Mask CPUID support in HWCAP on aarch64
valgrind currently does not know anything about the CPUID flag added to
the HWCAP auxv entry in kernel 4.11+
At runtime it will fails like this:
ARM64 front end: branch_etc
disInstr(arm64): unhandled instruction 0xD5380001
disInstr(arm64): 1101'0101 0011'1000 0000'0000 0000'0001 ==2082==
valgrind: Unrecognised instruction at address 0x4014e64.
This patch is a workaround by masking all HWCAP. This patch is dervied
