crypto/octeontx: enable build on non-Linux OS

Enabled build of Octeontx crypto PMD on non linux OS.
Other Octeontx PMDs are enabled already.

This is to avoid ABI test failure on an OS once we add dependency
between a driver which is built to another which is not.

Fixes: 8dc6c2f12e ("crypto/octeontx: add crypto adapter framework")
