don't use readFromSysfs on non-linux

Summary:
It eventually tries to read from /sys/devices which is not portable.
Let's just fall back to sysconf/CacheLocality::uniform.

This fixes a runtime crash on OSX, but CYGWIN/BSD were probably also
affected.
Closes #80

@override-unit-failures

Test Plan: author tested, contbuild, flib
