Fix for linux make check build failure

Fix for linux make check build failure

Linux make check is failing for mips, mips64, arm, arm64
with error:
"fatal error: mach/arm/vm_types.h: No such file or directory" in case of arm,
"../src/third_party/mac_headers/mach/machine/vm_types.h:37:2: error: #error architecture not supported" in case of mips/mips64

This was partially fixed in https://codereview.chromium.org/1645673002/.

Here excluding src/common/mac/macho_reader_unittest for hosts other than x86/x86-64.
