cpu-a: remove unused safe_intel_cpu_indicator_init routine

This was causing -fPIC link errors with icpc|gcc on Linux while linking a shared
library.  With this change I can build libx265.so, but the size is mysterious:

 629961 libx265.so
2477000 x265

The x265 executable requires libx265.so to be present to run, but the bulk of
the code seems to be in the executable itself.
